As part of the Pittsburgh International Airport's Creating a Sense of Place program, sponsored by the Richard King Mellon Foundation, Carnegie Mellon University has installed two displays at the airport that give travelers a chance to interact with CMU technology, and get a look at how research conducted at CMU is shaping the future of the world.

CMU has played a critical role in the region's resurgence as a high-tech hub, attracting talent and investment from around the world. With more than 13,000 students, the university hosts more than 70,000 visitors annually, from families and alumni to corporate, government, nonprofit and academic leaders.

EarthTime and IntraFace provide opportunities for visitors to explore technology from CMU's world-renowned School of Computer Science.

EarthTime

Location: Concourse D

Developed by the Community Robotics, Education and Technology Empowerment Lab (CREATE Lab) at CMU, EarthTime displays visualizations of Earth's transformations through natural changes and human impact. By rapidly combining huge sets of data with a vast number of images captured by NASA satellites between 1984 and 2016, users can explore issues like deforestation, movement of refugees, sea-level rise and surface water changes.

CREATE Lab empowers people to use technology to better their lives while promoting evidence-based decision-making, public discourse and action. In partnership with the World Economic Forum, CREATE Lab has demonstrated EarthTime to ministers, heads of state, non-governmental organizations (NGOs) and corporate leaders. Most recently, the technology was presented at New York City's Climate Week and in a TEDxGlobal Talk. It also has been used as a teaching tool in classrooms and by Kew Gardens in the United Kingdom for its annual "State of the World's Plants" report.

IntraFace

Location: Concourse C

The human face is one of the most powerful channels of non-verbal communication, conveying data about a person's emotional state, level of alertness and moods. Visitors to the IntraFace kiosk can explore how real-time facial image analysis software recognizes five basic expressions: happy, surprised, neutral, disgust or sad. Perhaps in keeping with the season, happiness has been the most common emotion registered by almost 30,000 people who have visited the kiosk since its launch in early November.

IntraFace is a project of the Human Sensing Lab at CMU's Robotics Institute. By sharing this open-source technology with the world's research community, scientists can pursue new ways to build intelligent systems that solve society's complex problems, including advancing the autism screening process, detecting terrorists in crowds and addressing distracted driving.


Human Rights Day: Aronson Helps Put Focus on Scientific Freedom

International Human Rights Day, Dec. 10, has a scientific focus this year. It coincides with the American Association for the Advancement of Science's (AAAS) recently released scientific freedom and responsibility statement, promoting scientific freedom and scientific responsibility.

"Human Rights Day is a time to reaffirm that we all possess certain basic rights that no individual, corporation, group or governmental entity can abridge or take from us," said Carnegie Mellon University's Jay D. Aronson, associate professor of science, technology and society in the Dietrich College of Humanities and Social Sciences' Department of History and director of CMU's Center for Human Rights Science (CHRS).

Aronson serves on the AAAS Committee on Scientific Freedom and Responsibility (CSFR), which developed the statement and has rolled out online resources for scientists, human rights advocates and policymakers. CSFR is an advisory committee to the AAAS Scientific Responsibility, Human Rights and Law program.

The CSFR's full statement reads:

Scientific freedom and scientific responsibility are essential to the advancement of human knowledge for the benefit of all. Scientific freedom is the freedom to engage in scientific inquiry, pursue and apply knowledge and communicate openly. This freedom is inextricably linked to and must be exercised in accordance with scientific responsibility. Scientific responsibility is the duty to conduct and apply science with integrity, in the interest of humanity, in a spirit of stewardship for the environment and with respect for human rights.

"The statement recognizes the societal value of science and the pursuit of knowledge, but just as importantly, it reminds those of us in positions of privilege that we have a responsibility to work to ensure human rights for all people around the world," Aronson said. "This duty is particularly strong at Carnegie Mellon, where we are building technologies and pioneering new knowledge that will have a profound impact on the planet and its peoples for generations to come."

Aronson said the statement is aspirational - it tells us how science and its relation to society ought to be and provides a framework to evaluate current and proposed research efforts in this regard. However, AAAS and the committee note that scientists' conduct is often constrained by a variety of political, economic and institutional factors.

To explore some of these issues, Aronson authored a supplemental article  that addresses the circumstances under which the ideals of scientific freedom and responsibility may fall short. The topics included: research in contexts where data and results cannot be freely collected or shared due to national security or economic concerns; doing research in non-democratic societies; and handling findings or data could be detrimental to society.

"Even though it may not be possible for scientists to uphold all of the values laid out in [the AAAS statement, they still must not use their knowledge, expertise, or creations to violate human rights or human dignity, cause unnecessary pain or suffering to non-human organisms, or disproportionate damage to the environment whenever it is possible to make another choice. Scientists should interpret restrictions, rules and directives that impinge on human rights and freedom as narrowly as possible and resist them when feasible," Aronson wrote.

Robin Mejia, manager of the CHRS Statistics and Human Rights program, believes scientific freedom is crucial to generating the kinds of data needed to assess and measure whether human rights are being violated. She notes that targeting scientists can be a way governments attempt to control data.

"A functioning democracy requires independence of agencies that gather and measure the data used to make policy decisions," said Mejia, who serves as vice chair of the American Statistical Association (ASA) Committee on Scientific Freedom and Human Rights. She has coordinated the ASA's response in the case of Andreas Georgiou, a Greek economist being targeted in his home country for producing accurate debt figures.

The United Nations will use Human Rights Day 2017 to kick off a year-long campaign to mark the upcoming 70th anniversary of the Universal Declaration of Human Rights a milestone document that proclaimed the inalienable rights that everyone is inherently entitled to as a human being - regardless of race, color, religion, sex, language, political or other opinion, national or social origin, property, birth or other status.

CMU Receives $7.5M in Federal BRAIN Initiative Funding

Researchers from Carnegie Mellon University's departments of Biological Sciences and Chemistry, Molecular Biosensor and Imaging Center (MBIC) and Pittsburgh Supercomputing Center (PSC) have received close to $7.5 million in new funding from the National Institutes of Health through the federal BRAIN Initiative to support innovative research and develop tools that will rapidly advance brain research.

"Carnegie Mellon's combined expertise in biology, psychology, computer science and engineering has positioned us to be at the forefront of creating new tools and technologies for neuroscience," said Alison Barth, professor of biological sciences, interim director of CMU's BrainHub neuroscience initiative and a member of the Center for the Neural Basis of Cognition. "The federal BRAIN Initiative's support is invaluable to increasing our understanding of how the brain communicates."

High Throughput Approaches for Cell-Specific Synapse Characterization

Marcel Bruchez, director of MBIC and professor of biological sciences and chemistry, and Barth were awarded more than $2 million to develop new tools and methods for high-throughput fluorescence synapse quantitation. They will work with the University of Pittsburgh's Simon Watkins, director of the Center for Biologic Imaging (CBI).

The human brain consists of billions of neurons, each of which passes information through thousands of synapses. Identifying how and where synapses develop under normal conditions and viewing how they change is vital to our understanding of learning, development and disease.

Image of dendritic spines
An image shows the ostsynaptic labeling of dendritic spines using fluorogen-activating proteins in a pyramidal neuron in the neocortex.

Fluorescence imaging has made it possible to identify specific cells among the sea of neurons in the brain and monitor how they are connected with one another. Under the new grant, the researchers will optimize reagents that will allow them to detect presynaptic and postsynaptic inputs and quantify synapse distribution between specific cell types in brain tissue. They will also develop software that will automate the analysis of the data, which was previously done by humans. This will allow researchers to count millions of neurons and billions of synapses, whereas previous studies were only able to look at small numbers of cells, or subcellular regions.

Confocal Fluorescence Microscopy Data Repository

Alexander J. Ropelewski, director of the biomedical application group at the PSC, Bruchez and Watkins received more than $5 million under the BRAIN Initiative Cell Census Network to build a confocal fluorescence microscopy data repository that will provide researchers with easy, searchable access to petabytes of neuroscience data.

New imaging tools and technologies, like large-volume confocal fluorescence microscopy, have greatly accelerated neuroscience research in the past five years, allowing researchers to image the whole brain at such a high level of resolution that they can zoom in to the level of a single neuron or synapse. These images, however, contain such a large amount of data — that only a small part of one brain's worth of data can be accessed at a time using a standard desktop computer. Additionally, images are often collected in different ways — at different resolutions, using different methodologies and different orientations. Comparing and combining data from multiple whole brains and datasets requires the power of supercomputing.

The Pittsburgh-based team will bring together MBIC and CBI's expertise in cell imaging and microscopy and pair it with the PSC's long history of experience in biomedical supercomputing to create a system called the Brain Imaging Archive. Researchers will be able to submit their whole brain images, along with metadata about the images, to the archive. There the data will be indexed into a searchable system that can be accessed using the internet. Researchers can search the system to find existing data that will help them narrow down their research targets, making research much more efficient.

Machine Learning Approaches for Electrophysiological Cell Classification

Barth was awarded more than $300,000 to develop a method to identify neural cell types from extracellularly recorded spike trains, a "Rosetta Stone" for decoding brain activity.

In a 500x500 micron column of brain tissue, there can be more than 60 different types of neuronal cells, each with its own properties. Currently researchers gather information from neurons by inserting an electrode into the brain and recording when neurons spike in response to a stimulus. While this reveals valuable information, researchers don't know which cell type they are recording.

Barth believes that researchers could determine cell type based on patterns found in a neuron's spike train. She will partner with researchers in Carnegie Mellon's Machine Learning Department and Language Technology Institute to develop classifiers for neuron types and use machine learning to identify cell type based on the pattern of spikes collected from a neuron.

Previously, Carnegie Mellon researchers received an additional $2.8 million from the BRAIN Initiative. Engineering faculty members Steven Chase and Byron Yu received over $850,000 from the National Science Foundation (NSF) to establish how variability in movement is encoded in the brain and how this variability contributes to learning and performance. Yu also received close to $1 million from the NSF to understand how the sensory environment and state of mind combine to affect perception and interpretation of the world around us. Max G'Sell, assistant professor of statistics received close to $1 million to study brain circuits in a real-world setting.

For Alumnus Dave Cotteleer, It's All About the Ride

By his own admission, Dave Cotteleer usually operates on gut instinct: If a move feels right, he is 100 percent in.

That philosophy of following his passion is the most logical way to explain what might seem, on its surface, as Cotteleer's unorthodox career path, from bank auditor to heavy metal rocker to vice president and managing director of the U.S. Market for Harley-Davidson. But in fact, each experience has informed the other, and collectively, they add up to what has been a lifelong pursuit of authenticity.

"Follow your passion. Don't sell out," said Cotteleer, a 1997 graduate with a master's degree of science in Industrial Administration from Carnegie Mellon University's Tepper School of Business. Cotteleer recently spoke to an audience of Tepper School MBA students as part of the W.L. Mellon Speaker Series. "Always be looking at opportunities that add something to you and something that you can be excited about."

After graduating with an undergraduate degree in finance, Cotteleer spent a brief stint working for a bank before joining a heavy metal band in 1994. He honed his business knowledge on the road by working with music industry executives, promoters and union workers at concert venues. The birth of his daughter dramatically altered his career trajectory, prompting him to apply to what is now the Tepper School to study operations.

"I run a lot on feel. And when I came here, it felt right," he said. "It's a decision that I have never regretted."

A summer internship at Harley-Davidson led to a full-time job offer, and he started as an information technology project manager in 1997.

"We were kind of, as a country and really in business, midway through what I term as the supply chain revolution," Cotteleer said. "It was when the whole world was waking up to the power of supply chain."

Despite a promising career start at Harley-Davidson, Cotteleer began to feel as though he was stagnating, so he left in 2005 for a job with the Sara Lee Corp. in Chicago. Although it was a bigger job and a bigger company, he now thinks it was a mistake.

"I didn't do it for the right reasons," he explained. "I thought that I loved the work of supply chain management, but the reality was I was chasing money and title."

That epiphany led him to realize a basic truth about his life, both inside and outside of the business world: Authenticity is key to effective leadership.

"Be authentic. Because the higher you go, the less truth you hear," he told the audience. "I believe that as soon as you become a manager, you have a moral obligation to be engaged and to be bought into where the organization is going."

He returned to Harley-Davidson, where he led the development of a new motorcycle designed specifically for the market in India, which in 2009 lifted some of its earlier restrictions on engine size. With no experience in product development or engineering, Cotteleer said he believes his leadership skills helped him make the project a success — a factor that also led to him earning the role of Harley's CIO in 2011, despite a relatively limited technology background.

Currently, Cotteleer said the company is working to apply technology to its iconic motorcycles in ways that younger riders expect and that its traditional customer base can readily embrace.

"The challenge that we face ... is how do we apply technology in our business, to our product, in a way that doesn't substantially alter the promise or the experience that people expect from Harley-Davidson?" he said, pointing out that countless people wear tattoos of the Harley-Davidson logo, one of the most recognizable brands on the planet.

He remains confident that he and his team at Harley will be up for the challenge. He credits his Tepper School education with helping him develop the problem-solving ability to effectively lead.

"After coming here, I realized there is no problem that can't be broken down, modeled, and solved," he said. "You can't survive this program unless you're really willing to dig in and work."

The journey continues for Cotteleer: Since his visit to campus, he has been promoted to an even more senior role as vice president and managing director of the U.S. Market for Harley-Davidson.

"Foundational science and math are at the core of CMU's education and research, and we are deeply grateful to Glen for ensuring that Dean Doerge and those who follow her will have the critical resources they need to advance the Mellon College of Science," Interim President Farnam Jahanian said. "Since graduating from MCS, Glen has built an extraordinary career at the intersection of science, business and medicine, and his work has revolutionized how we conduct medical research. His decision to give back to CMU at this time inspires all of us."

The gift will provide resources to the Mellon College of Science — which includes the biological sciences, chemistry, mathematical sciences and physics — to support promising initiatives, like interdisciplinary research into topics such as materials science, neuroscience and energy studies that link MCS to other areas of strength across the university; to recruit top students and faculty; and to expand MCS's research and instructional infrastructure.

"CMU had a profound effect on me, personally and professionally," de Vries said. "It is an incredible privilege to support the university, and to help perpetuate the dynamic learning environment in and around MCS."

The Mellon College of Science's research in foundational science is strengthened through the interdisciplinary nature of CMU, which encourages scientists to approach scientific questions using techniques from fields such as computer science, data science, automation and engineering.

Doerge, an interdisciplinary researcher whose own research spans biological sciences, statistics and data science, will be the first recipient of the Glen de Vries Dean's Chair. She was installed as dean of the Mellon College of Science in the fall of 2016, having previously been the head of the department of statistics at Purdue University.

"Glen is quintessentially CMU. He combined his expertise in biological sciences with computer science and data science along with his entrepreneurial spirit to address a pressing problem in health care," Doerge said. "He is truly an inspiration to all of our students, proving that there is no limit to what can be done with a CMU degree."

"Glen's historic gift is a resounding endorsement of the Mellon College of Science's importance to both Carnegie Mellon and the broader research community, and will allow us to take to the next level our commitment to an interdisciplinary, hands-on culture that molds students into supremely educated, well-rounded 21st century scientists and fosters innovative research," she added.

A New York native, de Vries received his undergraduate degree in molecular biology and genetics from Carnegie Mellon. He then worked as a research scientist at Columbia Presbyterian Medical Center and studied computer science at New York University's Courant Institute of Mathematics before starting Medidata in 1999.

Medidata is a life sciences technology provider that greatly enhances the way clinical research is designed, conducted and analyzed. Its integrated cloud-based platform is used by more than 950 organizations, and powers clinical trials for 18 of the world's top 25 global pharmaceutical companies and 18 of the top 25 medical device developers. In less than 20 years, it has grown from just two employees to about 2,000 employees in 14 locations and more than half a billion dollars in revenue annually. Medidata's software has supported more than 13,000 studies involving nearly four million patients.

In 2017, de Vries received the CMU Alumni Achievement Award. He is a member of the Carnegie Mellon University President's Global Advisory Council, and has returned to campus numerous times to speak with students and faculty, as well as recruit alumni to work at Medidata. He was an invited panelist during the university's recent 50th Anniversary Celebration at Homecoming Weekend. De Vries' previous philanthropy at CMU includes an endowed Presidential Fellowship in the biological sciences.

He is a Columbia HITLAB Fellow, a member of the Healthcare Businesswomen's Association European Advisory Board, and serves on the board of the Young Scientist Foundation, which prepares high school students for success at the university level through training and mentorship.

GeekWire Chooses Pittsburgh for Temporary HQ2

GeekWire is coming to Pittsburgh — at least for a while.

The Seattle-based technology news hub announced today that it will establish a second, temporary headquarters in Pittsburgh for the month of February. The idea to create a reporting outpost was prompted by the much-publicized Amazon HQ2, with GeekWire placing special emphasis on choosing a city that it considers a strong contender for the Amazon prize.

Carnegie Mellon University's School of Computer Science, with encouragement from colleagues at the University of Washington, last month submitted an invitation to GeekWire to consider Pittsburgh in its search. The SCS proposal emphasized local officials likely would not break their silence regarding details of the region's bid for the Amazon HQ2 bid, but contended the city had too many great stories to ignore.

Two or three reporters will arrive in Pittsburgh in late January to begin exploring Pittsburgh. Throughout February, they plan to write about the tech scene and examine the local food culture, public transportation, infrastructure, arts scene, economic development and other factors relevant to the Amazon search.

"We are excited to choose Pittsburgh as the home for GeekWire HQ2 — our temporary headquarters for the month of February," said John Cook, GeekWire co-founder. "Pittsburgh is undergoing an amazing rebirth, transforming itself into a world leader in the innovation economy. Interesting stories abound in Pittsburgh — from the cutting-edge research labs of Carnegie Mellon to the startup spaces of East Liberty to the influx of engineering talent.

"We look forward to telling those stories, and connecting with civic, tech and business leaders about a changing city, while at the same time indulging in the city's food renaissance and cheering on the Penguins."

The GeekWire staff, despite trepidation about February weather in southwestern Pennsylvania, picked Pittsburgh as one of four finalists, along with Denver, Cincinnati and Raleigh. Editors invited readers to vote their preference among the finalists. Pittsburgh was the runaway winner, with 50 percent of the votes.

"Is there a cooler tech city than Pittsburgh? I don't think so," said Andrew Moore, SCS dean. "That's why we always welcome writers, editors and photographers who have the talent to convey what's happening here to the larger world. GeekWire has an excellent reputation in Seattle and we are excited about them coming here to get better acquainted."

GeekWire was launched in March 2011 by Cook and Todd Bishop, both veteran journalists. The site covers technology developments throughout the Pacific Northwest and nationally, with 70 percent of its readership outside the Seattle region. It focuses special attention on hometown industry behemoths Amazon and Microsoft while covering research developments and tech startups in the region. It sponsors a number of events, such as the GeekWire Summit and GeekWire Cloud Tech Summit, and has a weekly radio show.

"GeekWire has grown to become a dominant tech news organization and an epicenter for the local technology community," according to the news site.

Though SCS extended an invitation, GeekWire will operate independently, just like any other news media outlet, and SCS will neither exercise control over editorial content nor favor GeekWire over other news outlets.

"We very much look forward to learning more about this historic American city, and how it is positioning for continued economic and societal vibrance in the coming years," Cook said. "If you have story ideas for our reporters or just want to tell us a great place to eat, please email us at hq2@geekwire.com."

Augmented Reality App Puts Museum Visitors in Touch with Architectural History

With the tap of a tablet, a Carnegie Mellon University-created augmented reality app puts museum visitors in touch with the stories behind historical plaster casts like those taken from The Tower of the Winds in Athens or the Assyrian Palace of Nineveh, near modern-day Mosul, Iraq.

Visitors to Carnegie Museum of Art's Hall of Architecture are testing the app, called Plaster ReCast, through May 6. The app already works with three casts in the hall's architectural plaster cast collection, which is the world's third-largest and includes monumental replicas of portions of buildings and fragments from across the Western world. Three more will be added in the spring.

CMU School of Architecture professors Francesca Torello and Joshua Bard researched the casts and created the framework and the content for the app, then worked with a team of students from CMU's Entertainment Technology Center to develop it. Together, they combined an understanding of history, architectural design and applied technology.

"Three branches of knowledge intersected to make this a meaningful application of augmented reality," Bard said. "That collaborative spirit and overlap of shared skill sets in the CMU community make projects like this possible."

On top of the tablet's camera view, the app can show users 3-D scans of the plaster casts, 3-D models of the original buildings from which the casts derive, and historical information on the original buildings. Augmented reality allows the user to access these layers of information without detracting from the museum experience.

"Being in the gallery with other people is part of what a museum is about," Torello said. "You're not by yourself with a webpage in front of you. You're there having an experience, and, on top of that, you can access all of this content."

Torello said that is important because, while the Hall of Architecture is grand and impactful, many people do not understand the meaning behind the pieces, and the appreciation for the craft of plaster casting has been lost.

"The public is often not aware of how a copy can be valuable in and of itself," Torello said. "In antiquity, for example, the Romans were making copies of Greek sculpture. So, the idea of seriality is, in reality, part of art history. In our society the authenticity of the art object has more importance, so these pieces have lost part of their clout."

Plaster ReCast is one of the projects featured in "Copy + Paste: Hall of Architecture," an eight-month study of the museum's Hall of Architecture. Over the course of "Copy + Paste," curators, technologists, students, architects and artists are testing ways of presenting information about the collection. The museum plans to use activities and visitor feedback to inform future efforts.

Alyssum Skjeie, project lead for "Copy + Paste" and program manager for The Heinz Architectural Center in CMoA, said the museum is curious to see how visitors react to the app and to find out whether certain features of the app enhance visitors' experience better than others.

"The whole idea is to provide visitors with information that they want, need and have asked for," Skjeie said. "This is a great way to test that."

She said CMoA's work with CMU not only has allowed it to develop an app covering a space rich with associations, it also is bringing CMU students back to the museum for a second HACLab.

CMU students will join the "Copy + Paste" effort in January through an architecture studio led by Bard. A couple days a week within one of the museum's galleries, students will work on projects that ultimately will become part of the exhibition. They will explore the material culture of architectural plaster, examining its historic importance and possible robotic applications.

The studio also will give the public a chance to talk with students, Bard said. Through that, he hopes museum visitors can learn more about the design process and create a public dialogue around it.

A team of students at Carnegie Mellon University in Qatar was awarded the Bronze Achievement Award at the International Genetically Engineered Machines (iGEM) competition hosted by the Massachusetts Institute of Technology in Boston. This is the first time CMU-Q has fielded a team at the annual iGEM competition, which included 310 teams from 44 countries.

The team developed an easy, quick way for the oil industry to test for biofilm build-up in offshore pipelines. A rapid and reliable test could help the oil industry reduce its use of biocides, which would lessen the negative impact on the marine ecosystem.

"This project is exciting because it has a practical application that can make a big impact on the health of the ecosystem in the waters around Qatar," said Annette Vincent, assistant teaching professor of biological sciences and the team's faculty adviser. Vincent said the next step is to develop a strain of harmless bacteria that would replace the biocide altogether.

The interdisciplinary student team includes Yasmin Abdelaal, Albandari Al-Khater, Dina Nayel Al Tarawneh, Najlaa Al-Thani, Aisha Fakhroo, Al-Reem Johar, Saad Rasool, Kawthar Alsadat Jafarian and Fatema Abdul Salik. The team received additional coaching by Cheryl Telmer, a research biologist at Carnegie Mellon's Pittsburgh campus.

The team will present the project at the Qatar Foundation Annual Research Conference in 2018.

The International Genetically Engineered Machine Foundation is an independent, nonprofit organization dedicated to education and competition, the advancement of synthetic biology, and the development of an open community and collaboration.

New Study Finds Carbon Capture and Utilization Won't Mitigate Global Warming

A study by four international scientists, including Carnegie Mellon University's Edward S. Rubin, questions the effectiveness of a proposed plan to mitigate global warming by using carbon dioxide (CO2) to produce fuels for transportation.

The approach, called carbon capture and utilization (CCU), would collect CO2 emitted by a power plant or industrial process and convert it to a liquid fuel using existing chemical technologies. CCU is being promoted by a number of researchers and organizations as a way to reduce the extraction of fossil fuels while also reducing CO2 emissions linked to climate change.

The new study published in the journal Energy & Environmental Science finds that CCU has little potential to mitigate climate change and could actually worsen the problem — unless the large amount of energy needed to manufacture the fuel comes from carbon-free sources, such as wind and solar.

"For that reason, proponents of CCU assume that all the energy needed is supplied by renewable energy," said Rubin, a co-author of the study.

Rubin and J. Carlos Abanades of the Spanish National Research Council, Marco Mazzotti of ETH Zurich and Howard J. Herzog of the MIT Energy Initiative presented their findings in a paper titled "On the climate change mitigation potential of CO2 conversion to fuels."

Rubin, the Alumni Chair Professor of Environmental Engineering and Science in Carnegie Mellon's Department of Engineering and Public Policy, and co-authors find that a far more effective approach to manufacturing transportation fuels is to use that renewable energy to decarbonize the electric power grid, while sequestering the CO2 from fossil fuel use deep underground.

"The result is a system that avoids far greater emissions of greenhouse gases, reduces the overall extraction of fossil fuel resources, and is less costly than a CO2 utilization scheme producing the same amount of fuel," said Rubin.

The researchers said they believe that while large-scale CO2 utilization sounds attractive, their analysis "shows that this concept has severe limitations as a mitigation measure or cost-effective strategy for reducing CO2 emissions."

The 2017 fellows are named inventors on nearly 6,000 U.S. patents, bringing the collective number of U.S. patents held by all NAI Fellows to more than 32,000. NAI Fellows were nominated by their peers for outstanding contributions to innovation in areas such as patents and licensing, innovative discovery and technology, significant impact on society, and support and enhancement of innovation.

Bhagavatula shares a number of patents related to facial recognition software and computer vision.

An interim vice provost for research at Carnegie Mellon, as well as a former associate dean for Graduate and Faculty Affairs in the College of Engineering, Bhagavatula will become the next director of CMU-Africa, effective, Jan. 1. CMU-Africa in Kigali, Rwanda, offers master's degree programs in electrical and computer engineering and information technology.

The 2017 NAI Fellows will be inducted April 5, 2018, as part of the Seventh Annual NAI Conference of the National Academy of Inventors in Washington, D.C. Andrew H. Hirshfeld, U.S. commissioner for patents, will provide the keynote address for the induction ceremony.

Bhagavatula received a bachelor's degree and master's degree in electrical engineering from the Indian Institute of Technology, Kanpur. He earned a Ph.D. in electrical engineering from Carnegie Mellon in 1980 before joining the faculty of CMU's Electrical and Computer Engineering Department in 1982. He has served as interim dean for the College of Engineering and as acting department head of Electrical and Computer Engineering.

Associate Professor Denis Colwell has received the Jack G. Buncher Chair and has been reappointed head of Carnegie Mellon University's School of Music, a position he has held since 2012.

"I look forward to another five years of Denis' innovative ideas, creative approaches, impactful pedagogical philosophy, and strategic-thinking skills, not to mention his passion for the school and its people," said College of Fine Arts Dean Dan Martin. "For these and so many other reasons, Denis is richly deserving of this tremendous honor made possible through the Buncher family."

The Buncher family established the chair with a $5 million gift to CMU's School of Music. To acknowledge the gift, longtime School of Music faculty member Marilyn Taft Thomas composed "The Buncher Suite" for violin soloist full orchestra. The CMU Philharmonic recorded the composition with University Professor Andres Cardenes as soloist, and Philharmonic Assistant Conductor and Music Director of the Contemporary Ensemble Daniel Nesta Curtis conducting. A recording of the piece and a documentary DVD will be given to the Buncher family as a gesture of gratitude, Colwell said.

Colwell trained as a trumpet player and completed his bachelor's of fine arts degree at Carnegie Mellon, studying under the legendary trumpeter Anthony L. Pasquarelli. He became assistant head of the school and, at the same time, served as music director of the CMU Wind Ensemble. He also directed and performed more than 1,400 concerts across the United States with Pittsburgh's River City Brass Band.

When Colwell became head of the Carnegie Mellon School of Music, he began to make positive changes almost immediately, Martin said. He made the management of the school more transparent and democratic, he instituted a number of initiatives that increased the quality of education and performance within the school, and he helped to engage the campus community with the school in a way that had not been accomplished before.

"It is a very great honor to be the first holder of the Jack G. Buncher Chair and to be reappointed as the head of the School of Music," Colwell said. "I want to very humbly thank and recognize all of my colleagues on the faculty and staff for their dedication and commitment to the school, and also our students — who work so very hard to continue the school's tradition of excellence. We are all enormously grateful to the Buncher family for their confidence in our school and for their magnificent generosity, the long-term benefits of whicih are nothing short of transformational. And, of course, thanks to my wife and daughter for their love, support and understanding."

Student-Athletes Honored at Fourth Annual Academic Achievement Celebration

Commitment, determination and dedication were frequent words spoken during this year's academic achievement celebration hosted by Carnegie Mellon University's Department of Athletics. Twenty-nine student-athletes paused during finals week to celebrate each other and their successes on and off the field.

Carnegie Mellon Interim President Farnam Jahanian said he is often on the sidelines cheering.

"I'm always struck by how impressive our student-athletes are," Jahanian said. "Whether through teamwork that you see on the field, on the court, or in classrooms, in our labs, and in our studios, our student-athletes are working together every day to reach new levels of achievement."

For the fourth year, juniors and seniors were feted who had an average grade-point average (GPA) of 3.72 or better. Of those, five had an average of 3.9 or higher, and three posted a perfect cumulative 4.0.

"The student-athletes invited to this celebration would not be here if they did not make a commitment to excellence upon their arrival to Carnegie Mellon," said Director of Athletics Josh Centor. "While academic success earned them their invitation, it is important to note that among the best students in the classroom are our best athletes."

Centor noted several team and individual accolades and shared that a student-athlete was spearheading a tutoring initiative that will have the Tartans working in a local elementary school almost every day next semester.

Senior men's basketball guard Thomas Cook, a first-generation college student in the Tepper School of Business, shared Jackie Robinson's quote — "A life has no impact except for the impact it has on other lives."

"I think that Carnegie Mellon student-athletes truly embody that, and I hope it continues in the future," Cook said.

Senior swimmer Kim Hochstedler spoke about the effort it takes to strive for greatness. Hochstedler swims the 100- and 200-yard breaststroke and the 200- and 400-yard individual medley.

"Whether it's a difficult practice or a challenging course, we all put our heart and our souls into everything we do here at Carnegie Mellon," said Hochstedler, who is studying psychology and statistics as part of the Science and Humanities Scholar Program. She is also an Andrew Carnegie Scholar. "It's not unusual to see an athlete start a school project weeks in advance or stay a few extra hours in lab, because we all strive for excellence in our academic pursuits. Similarly, it's not unusual to see an athlete stay after practice to stretch or run a few extra drills because we also strive for excellence in our sport."

Cook said the annual fall Student-Athlete Career Networking function is something unique to Carnegie Mellon.

"It's no surprise that every single year we have the most sought after employers come and recruit Carnegie Mellon student-athletes," Cook said. "It's a testament to our excellence and what we've produced and to the Athletics Department."

Cook also spoke about the Tartans' involvement in the community.

Four of CMU's teams have honorary captains from local and national children organizations, such as Friends of Jaclyn Foundation and Team Impact, which aims to improve the quality of life for children facing life-threatening and chronic illnesses by matching them with intercollegiate athletic teams. Through Team Impact, CMU's men's basketball team welcomed Camden Lookabaugh in 2014.

"The relationship we've built with Camden and Team Impact has been more rewarding than any individual accomplishment I've had in the classroom, on the court, or in my early career," Cook said.

Carnegie Mellon Reveals Inner Workings of Victorious AI

Libratus, an artificial intelligence that defeated four top professional poker players in no-limit Texas Hold'em earlier this year, uses a three-pronged approach to master a game with more decision points than atoms in the universe, researchers at Carnegie Mellon University report.

In a paper published online today by the journal Science, Tuomas Sandholm, professor of computer science, and Noam Brown, a Ph.D. student in the Computer Science Department, detail how their AI achieved superhuman performance by breaking the game into computationally manageable parts and, based on its opponents' game play, fix potential weaknesses in its strategy during the competition.

AI programs have defeated top humans in checkers, chess and Go — all challenging games, but ones in which both players know the exact state of the game at all times. Poker players, by contrast, contend with hidden information: what cards their opponents hold and whether an opponent is bluffing.

In a 20-day competition involving 120,000 hands at Rivers Casino in Pittsburgh this past January, Libratus became the first AI to defeat top human players at Head's-Up, No-Limit Texas Hold'em — the primary benchmark and longstanding challenge problem for imperfect-information game-solving by AIs.

Libratus beat each of the players individually in the two-player game and collectively amassed more than $1.8 million in chips. Measured in milli-big blinds per hand (mbb/hand), a standard used by imperfect-information game AI researchers, Libratus decisively defeated the humans by 147 mmb/hand. In poker lingo, this is 14.7 big blinds per game.

"The techniques in Libratus do not use expert domain knowledge or human data and are not specific to poker," Sandholm and Brown said in the paper. "Thus, they apply to a host of imperfect-information games." Such hidden information is ubiquitous in real-world strategic interactions, they noted, including business negotiation, cybersecurity, finance, strategic pricing and military applications.

Libratus includes three main modules, the first of which computes an abstraction of the game that is smaller and easier to solve than by considering all 10161 (the number 1 followed by 161 zeroes) possible decision points in the game. It then creates its own detailed strategy for the early rounds of Texas Hold'em and a coarse strategy for the later rounds. This strategy is called the blueprint strategy.

One example of these abstractions in poker is grouping similar hands together and treating them identically.

"Intuitively, there is little difference between a king-high flush and a queen-high flush," Brown said. "Treating those hands as identical reduces the complexity of the game and, thus, makes it computationally easier." In the same vein, similar bet sizes also can be grouped together.

But in the final rounds of the game, a second module constructs a new, finer-grained abstraction based on the state of play. It also computes a strategy for this subgame in real-time that balances strategies across different subgames using the blueprint strategy for guidance — something that needs to be done to achieve safe subgame solving. During the January competition, Libratus performed this computation using the Pittsburgh Supercomputing Center's Bridges computer.

When an opponent makes a move that is not in the abstraction, the module computes a solution to this subgame that includes the opponent's move. Sandholm and Brown call this nested subgame solving. DeepStack, an AI created by the University of Alberta to play Heads-Up, No-Limit Texas Hold'em, also includes a similar algorithm, called continual re-solving. DeepStack has yet to be tested against top professional players, however.

The third module is designed to improve the blueprint strategy as competition proceeds. Typically, Sandholm said, AIs use machine learning to find mistakes in the opponent's strategy and exploit them. But that also opens the AI to exploitation if the opponent shifts strategy. Instead, Libratus' self-improver module analyzes opponents' bet sizes to detect potential holes in Libratus' blueprint strategy. Libratus then adds these missing decision branches, computes strategies for them, and adds them to the blueprint.

In addition to beating the human pros, Libratus was evaluated against the best prior poker AIs. These included Baby Tartanian8, a bot developed by Sandholm and Brown that won the 2016 Annual Computer Poker Competition held in conjunction with the Association for the Advancement of Artificial Intelligence Annual Conference. Whereas Baby Tartanian8 beat the next two strongest AIs in the competition by 12 (plus/minus 10) mbb/hand and 24 (plus/minus 20) mbb/hand, Libratus bested Baby Tartanian8 by 63 (plus/minus 28) mbb/hand. DeepStack has not been tested against other AIs, the authors noted.

"The techniques that we developed are largely domain independent and can thus be applied to other strategic imperfect-information interactions, including nonrecreational applications," Sandholm and Brown concluded. "Due to the ubiquity of hidden information in real-world strategic interactions, we believe the paradigm introduced in Libratus will be critical to the future growth and widespread application of AI."

The technology has been exclusively licensed to Strategic Machine Inc., a company founded by Sandholm to apply strategic reasoning technologies to many different applications.

A paper by Brown and Sandholm regarding nested subgame solving recently won a Best Paper award at the Neural Information Processing Systems (NIPS 2017) conference. Libratus received the HPCwire Reader's Choice Award for Best Use of AI at the 2017 International Conference for High Performance Computing, Networking, Storage and Analysis (SC17).

Smartly designed and implemented behavioral interventions change the way people make decisions, alter the way organizations operate and influence how policies are put into place. Now, students looking to do cutting-edge research at the intersection of economics and psychology can get the first and only Ph.D. in behavioral economics at Carnegie Mellon University.

"This new Ph.D. program builds on our world-renowned behavioral economics faculty at the Department of Social and Decision Sciences and economics faculty from the Tepper School of Business," said Linda Babcock, the James M. Walton Professor of Economics and the head of the Social and Decision Sciences Department. "We are thrilled to be able to offer this unique graduate degree program that will focus on basic and applied research and complements our undergraduate degree in behavioral economics, policy, and organizations, also the first-of-its-kind."

Because it is a joint program through the Dietrich College's Department of Social and Decision Sciences and the Tepper School, students will have access to world-renowned experts in decision science, organizational behavior, statistics, marketing and many other areas. Research facilities like the Center for Behavioral and Decision Research and BEDR Policy Lab also will be key resources for students.

"The CMU economics Ph.D. program has a long tradition of rigorous training in economics and econometrics that launches students into economics research," said Chris Sleet, head of Economics. "I am excited that this will now be combined with exposure to psychology and state-of-the-art training in behavioral economics. This new combination will allow students to undertake path breaking research at the intersection of economics and psychology."

The roots of behavioral economics started at CMU, with the late Herbert Simon, a Nobel laureate in economics, and current faculty member George Loewenstein, a co-founder of the field. The Tepper School is distinguished by the nine Nobel laureates in economics who have served on its faculty or studied in its economics Ph.D. program. Nobel laureate Finn Kydland currently holds the Richard P. Simmons Distinguished Professorship at the Tepper School.

Carnegie Mellon's approach to the discipline is unique. CMU researchers use a distinct fusion of psychology and economics to tackle some of the world's most complicated and costly problems. And they design and test multifaceted interventions to change the way we make decisions, alter the way organizations operate and influence how policies are implemented.


Learning by Doing Good

A rural farmer in India looks at an iPad

Carnegie Mellon University students love to create cool new technologies, but as students discovered in a course that debuted this fall, sometimes it can be even more rewarding to apply existing technologies in new ways that can unite communities or perhaps save lives.

In the project course "Computing for Good," several dozen students used satellite imagery to detect illegal mines in the Congo, created apps to coordinate timely pickup of harvested crops in Columbia and designed an augmented reality system to show farmers in Rwanda how investments in irrigation systems would improve their land.

"I believe if something has a meaning, a purpose, it engages students more and they learn more," said Afsaneh Doryab, a systems scientist in the Human-Computer Interaction Institute who taught the course with Anind Dey, the then-HCII director. "In the School of Computer Science, education is about more than just theoretical knowledge; students learn by doing good."

One team of students worked with an NGO in India to help marginal farmers who, burdened by debt, commit suicide at the rate of 16,000 a year. The students designed a profit prediction tool to show farmers the likely yield and profits from more than a dozen crops, including maize, cotton, sugar cane, rice and urad beans.

Xinwen Liu, a sophomore in information systems, explained that the computer program factors in such variables as size of the farm, rainfall, temperatures, the farmer's budget and the farmer's debt to calculate potential profits from a crop.

The program and its user interface were field tested three times by the NGO in Odisha, a state on the eastern coast of India where 50 percent of farmers are considered marginal, to gauge the level of interest in the technology and the usability of the interface.

Another team member and Odisha native, senior interdisciplinary major Svayam Mishra, said farmers there do not tend to change crops much, even when crop yields dip or the marketability of the crops decline. By providing crucial information not otherwise available, the profit-predicting tool could enable farmers to seriously consider switching to more promising crops, he added.

HCII master’s student Shen Lu presents a mockup of the Homestead smokestack projection scheme that her team developed to support a community walking program.

Closer to home, another team worked with officials in West Homestead to devise a walking app that would encourage borough residents to be more physically active and help increase cohesiveness in a community that includes both older, lifelong residents and millennials seeking cheap housing.

Originally the idea of a borough council member, the "Let's Walk" program envisioned by the students would gamify fitness, giving participants an opportunity to earn points that can be exchanged for goods with local merchants. The program also would provide a smartphone interface that helps connect users with other walkers, encouraging good-natured competition, said Hamza Qureshi, a junior architecture student.

A unique aspect of the program takes advantage of the row of smokestacks from the old Homestead Works, now a signature feature of the Waterfront development in Homestead. Team member Shen Lu, a HCII master's degree student, said a series of projectors would shine participants names and walking achievements on the smokestacks as they walked by.

Cindy Bahn, borough manager, said Waterfront management has already shown support for the projector concept and the borough is seeking funding to make Let's Walk a reality for its 6,000 residents.

"They've been a dream team," Bahn said of the five-member team, noting she hoped many would be able to continue with the program beyond the semester.

Doryab said students would be able to continue their projects as independent study in the spring. Student groups such as Design for America and Tech4Society also might be involved in some of the ongoing work, she added.

"The students have been really enthusiastic about what they are doing," she said. "We want to help them see this through."

From a record-number of women in the first-year class to groundbreakings for buildings that will be home to future innovative work and learning, the news has been filled with stories about researchers and students enriching the everyday human experience both at Carnegie Mellon University and around the world. Here is a selection of some of the top stories from the past year:

Machine Learning Will Change Jobs

Machine learning computer systems, which get better with experience, are poised to transform the economy much as steam engines and electricity have in the past. They can outperform people in a number of tasks, though they are unlikely to replace people in all jobs.

So say Carnegie Mellon University's Tom Mitchell and The Massachusetts Institute of Technology's Erik Brynjolfsson in a Policy Forum commentary published in the Dec. 22 edition of the journal Science. Mitchell, who founded the world's first Machine Learning Department at CMU, and Brynjolfsson, director of the MIT Initiative on the Digital Economy in the Sloan School of Management, describe 21 criteria to evaluate whether a task or a job is amenable to machine learning (ML).

"Although the economic effects of ML are relatively limited today, and we are not facing the imminent 'end of work' as is sometimes proclaimed, the implications for the economy and the workforce going forward are profound," they write. The skills people choose to develop and the investments businesses make will determine who thrives and who falters once ML is ingrained in everyday life, they argue.

ML is one element of what is known as artificial intelligence. Rapid advances in ML have yielded recent improvements in facial recognition, natural language understanding and computer vision. It already is widely used for credit card fraud detection, recommendation systems and financial market analysis, with new applications such as medical diagnosis on the horizon.

Predicting how ML will affect a particular job or profession can be difficult because ML tends to automate or semi-automate individual tasks, but jobs often involve multiple tasks, only some of which are amenable to ML approaches.

"We don't know how all of this will play out," acknowledged Mitchell, the E. Fredkin University Professor in CMU's School of Computer Science. Earlier this year, for instance, researchers showed that a ML program could detect skin cancers better than a dermatologist. That doesn't mean ML will replace dermatologists, who do many things other than evaluate lesions.

"I think what's going to happen to dermatologists is they will become better dermatologists and will have more time to spend with patients," Mitchell said. "People whose jobs involve human-to-human interaction are going to be more valuable because they can't be automated."

Tasks that are amenable to ML include those for which a lot of data is available, Mitchell and Brynjolfsson write. To learn how to detect skin cancer, for instance, ML programs were able to study more than 130,000 labeled examples of skin lesions. Likewise, credit card fraud detection programs can be trained with hundreds of millions of examples.

ML can be a game changer for tasks that already are online, such as scheduling. Jobs that don't require dexterity, physical skills or mobility also are more suitable for ML. Tasks that involve making quick decisions based on data are a good fit for ML programs; not so if the decision depends on long chains of reasoning, diverse background knowledge or common sense.

ML is not a good option if the user needs a detailed explanation for how a decision was made, according to the authors. In other words, ML might be better than a physician at detecting skin cancers, but a dermatologist is better at explaining why a lesion is cancerous or not. Work is underway, however, on "explainable" ML systems.

Understanding the precise applicability of ML in the workforce is critical for understanding its likely economic impact, the authors say. Earlier this year, a National Academies of Sciences, Engineering and Medicine study on information technology and the workforce, co-chaired by Mitchell and Brynjolfsson, noted that information technology advances have contributed to growing wage inequality.

"Although there are many forces contributing to inequality, such as increased globalization, the potential for large and rapid changes due to ML, in many cases within a decade, suggests that the economic effects may be highly disruptive, creating both winners and losers," they write. "This will require considerable attention among policy makers, business leaders, technologists and researchers."

Host Families Provide “Comforts of Home” to International Students

Christine Asenjo and Anit Sahu

When Anit Kumar Sahu returns from Winter Break to resume his doctoral studies at Carnegie Mellon University, he will be 10,000 miles from his family in India. But thanks to his host family in Pittsburgh, he will enjoy a few of the “comforts of home” while he is here.  
 
“One of my favorite stress busters is cooking. When my host family invited me to cook some old-school Indian food for them at their place, nothing made me more happy than that,” Sahu said.
 
Sahu’s host family is the family of Christine Asenjo, a CMU staff member who coordinates international programs at the university. Asenjo invites Sahu to her family’s birthday and holiday celebrations and other informal gatherings.
 
“Getting a few hours away from work to spend in a welcoming family environment helps me with the stress levels considerably. I feel my home has moved 10,000 miles closer. I have gotten to know Pittsburgh well through Christine and her family, and for every occasion, I have a family here to share it with,” Sahu said.
 
The Host Family Program for international students is part of a university-wide effort to enhance the CMU student experience by facilitating greater engagement between students and CMU faculty, staff, alumni and local families. The program gives international students the opportunity to explore Pittsburgh with their hosts, engage in meaningful dialogue, practice their English, and generally enjoy a connection to the city they might not otherwise experience.
 
The program was started by Jimmy Hsia, vice provost for International Programs and Strategy, who benefitted from a similar program while he was in the United States working toward his Ph.D. in mechanical engineering 30 years ago.
 
“If you look at our domestic students, before they enroll they have visited campus, and sometimes they already know somebody here. That type of connection for many if not all international students is not there,” said Hsia, a native of China. “Before they enroll, most of them have never even taken the campus tour. So, when they arrive there is a cultural shock. That puts a lot of pressure on these international students.”
 
Hsia said most of the international students in the program are master’s degree students, and “when they come, they jump right into their work. You can imagine many of them need support, need some social circle as a support structure,” Hsia said.
 
Before the Host Family Program, Hsia said students identified and socialized only with students from their home country.
 
“That is what we want to avoid,” Hsia said. “We want them to come here to be part of the community, rather than be siloed with their own countrymen and countrywomen. Now that we have run it for one and a half years, we see there is a benefit for the host families as well.”
 
Singles, couples and families with children are all welcome to apply to be hosts. So far this academic year, Asenjo has matched 131 students with 81 hosts. Richard Kepple and his wife, Gail, typically meet with their students four to five times during the semester. Currently, they are hosting Taruna Vardha (center, above photo).
 
“The students have a hard time tearing themselves away from their studies, so sharing a meal has been a good option. They need to eat anyway!” Kepple said.

The Kepples share a coffee with their international student

The Kepples have found that a simple breakfast together tends to be a mutually enjoyable experience. They also have spent time with their students at local museums and theatrical and dance performances.
 
“It’s wonderful to meet young people from different cultures and learn about their lives,” said Kepple, who is director of advancement research at CMU. “It’s also rewarding to introduce them to Pittsburgh and to provide some insight into at least a small slice of American culture.”
 
Lyn Krynski and her husband, members of CMU’s Osher Lifelong Learning Institute, have hosted a student from China who, like Sahu, enjoyed the opportunity to cook and share authentic cuisine from his home country. They also hosted a student from India after he had returned from a summer internship in California.
 
“It was fascinating to hear about his work experience in a field that is mostly unknown to us,” Krynski said. “Often we invited other friends from our social circle to join us.  It always expanded the conversation, and everyone took something away from the experience.”  
 
Krynski said both students expressed the value of having supportive people to relax with and to ease the rigor of academic life.
 
“To be ‘that person’ for them has been a joy,” Krynski said.

Happy New Year!
