M. Brian Blake is a professor of computer science and associate dean of engineering at the University of Notre Dame. His research interests include the investigation of automated approaches to sharing information and software capabilities across organization boundaries, sometimes referred to as enterprise integration. His investigations cover the spectrum of software engineering: design, specification, proof of correctness, implementation/experimentation, performance evaluation, and application. Blake’s long-term vision is the creation of adaptable software entities or software agents that can be deployed on the Internet and, using existing resources, can manage the creation of new processes, sometimes referred to as interorganizational workflow. He has several ongoing projects that make incremental progress toward this long-term vision. In addition, he conducts experimentation in the areas of software engineering education and software process and improvement to determine the most effective methods for training students and professionals to develop module systems that by nature are distributed. Blake has consulted for such companies as General Electric, Lockheed Martin, General Dynamics, and the MITRE Corporation. He has published more than 95 refereed journal papers and conference proceedings in the areas of service-oriented computing, agents and workflow, enterprise integration, component-based software engineering, distributed data management, and software engineering education. Blake’s work has been funded by the Federal Aviation Administration, the MITRE Corporation, the National Science Foundation, DARPA, the Air Force Research Laboratory, SAIC, and the National Institutes of Health. He earned his doctorate in information technology and computer science from George Mason University.
Robert Constable is the dean of the Faculty of Computing and Information Science at Cornell University. Formerly he was the chair of the Computer Science Department for 6 years. He also heads a research group in automated reasoning and formal methods in the Computer Science Department, where he is a professor. Constable is a graduate of Princeton University, where he worked with Alonzo Church, one of the pioneers of computer science. He did his Ph.D. work at the University of Wisconsin with Stephen Cole Kleene, a Ph.D. student of Church and another pioneer of computer science. Church traces his mathematical lineage back to Gottfried Wilhelm Leibniz, one of the first logicians interested in mechanical computation and the digitization of human knowledge. Constable joined the Cornell University faculty in 1968. He has supervised more than 43 Ph.D. students in computer science. He is known for work in connecting programs and mathematical proofs that has led to new ways of automating the production of reliable software. This work is known by the slogan “proofs as programs,” and it is embodied in the Nuprl (“new pearl”) theorem prover. He has written three books on this topic as well as numerous research articles. Since 1980 he has headed a project that uses Nuprl to design and verify software systems, instances of which are still operational in industry and science. Currently he is working on extending this programming method to concurrent processes, realizing the notion of “proofs as processes.” In 1999 he became the first dean of the Faculty of Computing and Information Science, a unit that includes the Computer Science Department, the Department of Statistical Science, the Information Science Program, and the Program in Computer Graphics. It also sponsors the undergraduate major and graduate field in computational biology.
Yasmin B. Kafai is a professor at the Graduate School of Education, University of Pennsylvania. In addition, she spent more than a decade on the faculty at the UCLA Graduate School of Education and Information Studies. As a learning scientist, she has researched and developed media-rich software tools and environments—most recently Scratch, together with researchers at the MIT Media Lab—that support youth in schools and community centers in becoming designers of games, simulations, and virtual worlds. As part of her policy initiatives, she wrote Under the Microscope: A Decade of Gender Equity Interventions in the Sciences (2004) and participated in the national commission that produced the report TechSavvy Girls: Educating Girls in the Computer Age (2000) for the American Association of University Women. She also briefed the Computer Science and Telecommunications National Research Council report Being Fluent with Information Technology (National Academy Press, Washington, D.C., 1999). While conducting research at the Massachusetts Institute of Tech-
nology Media Laboratory, she received her Ed.D. in human development and psychology from Harvard University.
Janet L. Kolodner is a Regents’ Professor in the School of Interactive Computing at Georgia Institute of Technology. Her research over the past 30 years has addressed a wide variety of issues in learning, memory, and problem solving, both in computers and in people. During the 1980s, she pioneered the computer method called case-based reasoning, which allows a computer to reason and learn from its experiences. The first case-based design aids (CBDAs) came from her lab. Archie-2, for example, helped architecture students with conceptual design. During the early 1990s, she used the cognitive model implied by case-based reasoning to address issues in creative design. JULIA planned meals, Creative JULIA figured out what to do with leftover rice, IMPROVISOR did simple mechanical design, and ALEC simulated Alexander Graham Bell in his invention of the telephone. Later in the 1990s, she used the cognitive model in case-based reasoning to guide the design of a science curriculum for middle school. Learning by Design™ is a design-based learning appoach and an inquiry-oriented project-based approach to science learning that has children learn science from their design experiences. The sequencing of activities in the classroom encourages students to reflect on their design and science experiences in ways that case-based reasoning says are appropriate for integrating them well into memory. Learning by Design curriculum units and the sequencing structures in Learning by Design are being integrated into a full 3-year middle-school science curriculum called Project-Based Inquiry Science (PBIS). Most recently, Kolodner’s research uses what she learned in designing Learning by Design to create informal learning environments to help middle schoolers come to think of themselves as competent scientific reasoners. In Kitchen Science Investigators, fifth and sixth graders learn science in the context of cooking. In Hovering Around, they learn about motion and forces, about airflow, and about how to explain in the context of designing hovercraft. Kolodner is founding editor in chief of the Journal of the Learning Sciences and is a founder and first executive officer of the International Society for the Learning Sciences. She has headed up the Cognitive Science Program at Georgia Tech and headed an organization called EduTech in the mid-1990s whose mission was to use what is known about cognition to design educational software and integrate it appropriately into educational environments. She has a B.S. from Brandeis University in math and computer science and an M.S. and a Ph.D. in computer science from Yale University.
Lawrence Snyder is a professor of computer science and engineering at the University of Washington in Seattle. Snyder’s research has focused on
parallel computation, including architecture, algorithms, and languages. He has served on the faculties of Yale and Purdue universities and has had visiting appointments at UW, Harvard, MIT, Sydney University, the Swiss Technological University, the University of Auckland, and Kyoto University. In 1980 he invented programmable interconnect, a method to dynamically configure on-chip components, and a technology used today for FPGAs. In 1990 he was co-designer of Chaos Router, a randomizing adaptive packet router. He was the principal investigator of the ZPL language design project, the first high-level parallel language to achieve “performance portability” across all parallel computer platforms. Snyder is the author of Fluency with Information Technology: Skills, Concepts and Capabilities, a textbook for non-techie college freshmen that teaches fundamental computing concepts; the book is in its third edition. With former Ph.D. student Calvin Lin (University of Texas, Austin), he has written Principles of Parallel Programming, published in 2008. Snyder was a three-term member of the Computer Research Association Board of Directors, developing a series of best-practices white papers. He chaired the NSF CISE Advisory Board as well as several CISE directorate oversight panels and numerous review panels. The two National Research Council studies that he chaired produced influential reports—Academic Careers for Experimental Computer Scientists and Engineers (1994) and Being Fluent with Information Technology (1999). He served three terms on the NRC’s Army Research Laboratory Technical Advisory Board. He serves on ACM’s Education Board, has been general chair or program committee chair of several ACM and IEEE conferences, and is a fellow of both the ACM and the IEEE. He received a B.A. from the University of Iowa in mathematics and economics and his Ph.D. from Carnegie Mellon University as a student of A. Nico Habermann.
Uri Wilensky is a professor of learning sciences and computer science at Northwestern University and holds appointments in the cognitive science program and in complex systems. He is the founder and current director of the Center for Connected Learning and Computer-Based Modeling and also a founder and member of the governing board of the Northwestern Institute on Complex Systems (NICO). His most recent projects focus on developing tools that enable users (both researchers and learners) to simulate, explore, and make sense of complex systems. His NetLogo agent-based modeling software is in widespread use worldwide. Prior to coming to Northwestern, he taught at Tufts University and MIT and was a research scientist at Thinking Machines Corporation. Wilensky is a founder and an executive editor of the International Journal of Computers for Mathematical Learning. His research interests include computer-based modeling and agent-based modeling, STEM education, mathematics in the context
of computation, and complex systems. He is a recipient of the National Science Foundation’s Career Award as well as the Spencer Foundation’s Post-Doctoral Award. He has directed numerous NSF research projects focused on developing computer-based modeling tools and studying their use. Among these tools are multi-agent modeling languages such as StarLogoT and NetLogo, model-based curricula such as GasLab, ProbLab, NIELS, and BEAGLE Evolution, and Participatory Simulation Toolkits such as Calc-HubNet and Computer-HubNet. The tools enable learners to explore and create simulations of complex phenomena across many domains of the natural and social sciences and, through creating and exploring such simulations, deepen their understanding of core scientific concepts. Many of these tools are also in use by researchers across a wide variety of domains including the natural sciences, social sciences, business, and medicine. By providing a “low-threshold” language for exploring and constructing models, Wilensky hopes to promote modeling literacy—the sharing and critiquing of models in the scientific community, in education, and in the public at large. Wilensky did his undergraduate and graduate studies in mathematics, philosophy, and computer science at Brandeis and Harvard universities and received his Ph.D. in media arts and sciences from the Massachusetts Institute of Technology.
Dor Abrahamson specializes in the study of mathematical intuition, reasoning, and learning from the synergistic perspectives of cognitive and sociocultural theory. He investigates in particular the roles that mediated, reflexive interaction with a range of technologies plays in students’ content-focused and intellectual development, which he views as trajectories from intuition to inscription. A core aspect of Abrahamson’s professional practice is the design, production, implementation, and evaluation of innovative mixed-media concept-targeted curricular artifacts aligned with the emerging empiricism of individual cognition in social context. Operating in design-based research methodology, Abrahamson is particularly interested in instances of spontaneous multimodal coordination of distributed epistemic and material resources and in the roles of teachers in facilitating conceptual insight. Abrahamson also explores the impact of complexity studies’ perspectives and methodologies on education research and has been arguing for the use of agent-based modeling to advance theories of individual learning in social context. During his tenure as a Spencer Postdoctoral Fellow, Abrahamson developed computer-based modules for learning probability. He has published in the Handbook of Mathematical Cognition, International Journal of Computers for Mathematical Learning (and is a member of the editorial board), Educational Studies in Mathematics,
Cognition & Instruction, For the Learning of Mathematics, Mathematics Teaching in the Middle School, and the Journal of Statistics Education, and he contributes regularly to major international conferences. He received his M.A. in cognitive psychology in 2000 from Tel Aviv University, Israel, and a Ph.D. in learning sciences in 2004 from Northwestern University.
Kevin Ashley holds interdisciplinary appointments as a faculty member of the Graduate Program in Intelligent Systems at the University of Pittsburgh, a senior scientist at the Learning Research and Development Center, a professor of law, and an adjunct professor of computer science. His goals are to contribute to artificial intelligence (AI) research on case-based and analogical reasoning, argumentation, and explanation and to develop instructional and information retrieval systems for professionals in case-based domains such as law and ethics. Currently, he and his students are pursuing research projects in automatically indexing legal case texts, engaging law students in online argumentation dialogues, intelligent retrieval of ethics codes and cases, and Web-based tutoring to help students get more from reading ethics cases. For his Ph.D., he developed an AI CBR system, HYPO, which reasons by analogy to past legal cases, makes arguments about legal fact situations, and poses hypothetical cases. MIT Press/Bradford Books published his book, based on his dissertation, entitled Modeling Legal Argument: Reasoning with Cases and Hypotheticals. In April 1990, the National Science Foundation selected Professor Ashley as a Presidential Young Investigator, and in 2002 he was selected as a fellow of the American Association of Artificial Intelligence. From June 1988 through July 1989, he was a visiting scientist at the Thomas J. Watson Research Center, Yorktown Heights, New York. For 4 years prior to his computer science graduate work, he was an associate attorney at White & Case, a large Wall Street law firm. While a philosophy major at Princeton, he was a research assistant for Professor Walter Kaufmann. He received a B.A. in philosophy (magna cum laude) from Princeton University in 1973, a J.D. (cum laude) from Harvard Law School in 1976, and a Ph.D. in computer science in 1988 from the University of Massachusetts, where he held an IBM Graduate Research Fellowship.
Owen Astrachan is a professor of the practice of computer science at Duke University and the department’s director of undergraduate studies for teaching and learning.

Joshua Danish’s research examines the role of external representations, such as drawings, maps, and computer simulations, in supporting cognition and learning. To study learning and development in classroom contexts, he employs cultural historical activity theory to articulate the influence of various mediators—the physical tools, rules, division of labor, and local community—on students’ activities as they learn and develop. Recent research has included the development and study of BeeSign, a computer simulation and accompanying curriculum that engages kindergarten and first-grade students in learning about the nectar-gathering behavior of honeybee hives; the Community Mapping Project, in which seventh-grade students learned basic statistics concepts using the MyWorld Geographical Information Systems mapping software to study
local community issues; and the Semiotic Pivots and Activity Spaces for Elementary Science project, which takes advantage of sensing technologies and augmented reality tools to support first- and second-grade students in learning about physical science concepts.

His current projects include shape modeling for traumatic brain injury simulations, and the NSF-supported SECANT project teaching computational thinking to science majors.
Ken Kahn is a senior researcher at Oxford University and the London Knowledge Laboratory. His interest in programming languages for children was sparked while he was a Ph.D. student at the MIT AI Laboratory in the 1970s. While at the MIT AI Lab, he worked with Seymour Papert and others in the Logo Group. After 15 years as a researcher in programming languages and AI, he returned to children’s programming languages when he founded Animated Programs to develop ToonTalk. ToonTalk is an advanced programming language that looks like a video game. Children as young as 3 have successfully used it to create programs by training virtual robots to do actions such as giving birds messages to deliver, loading up trucks, and putting things in boxes. Kahn participated in two large-scale European projects in which children built computer games using ToonTalk. More recently he has been designing and building construction kits that enable students to build computer simulations by composing transparent modules.
Alan Kay, president of Viewpoints Research Institute, Inc., is one of the earliest pioneers of object-oriented programming, personal computing, and graphical user interfaces. His contributions have been recognized with the Charles Stark Draper Prize of the National Academy of Engineering “for the vision, conception, and development of the first practical networked personal computers”; the Alan. M. Turing Award from the Association for Computing Machinery “for pioneering many of the ideas at the root of contemporary object-oriented programming languages, leading the team that developed Smalltalk, and for fundamental contributions to personal computing”; and the Kyoto Prize from the Inamori Foundation “for creation of the concept of modern personal computing and contribution to its realization.” This work was done in the rich context of the Advanced Research Projects Agency (ARPA) and the Xerox Palo Alto Research Center (PARC) with many talented colleagues. He is an elected fellow of NAE and AAAS, as well as a member of RSA, ACM, and CHM. At Viewpoints Research Institute he and his colleagues continue to explore advanced systems and programming design by aiming
for a “Moore’s law” advance in software creation of several orders of magnitude. Kay and Viewpoints are also deeply involved in the One Laptop Per Child initiative that seeks to create a Dynabook-like “$100 laptop” for every child in the world (especially in the third world). Kay has a B.A. in mathematics and biology, with minor concentrations in English and anthropology, from the University of Colorado, 1966. He also holds an M.S. and a Ph.D. in computer science (1968 and 1969, both with distinction) from the University of Utah.
Peter Lee is the head of the Computer Science Department at Carnegie Mellon University. In this capacity, he oversees a computing organization whose research and education programs are consistently ranked among the top four in the nation. Prior to assuming his current position, Lee was the vice provost for research, providing administrative oversight and strategic guidance for Carnegie Mellon’s research activities, an enterprise that exceeds $400 million annually in sponsored research. Lee is an active researcher, educator, administrator, and servant to the academic community. For his research, he has received several awards, including the ACM SIGOPS Hall of Fame Award, and election as an ACM Fellow. He is a member of the board of directors of the Computing Research Association (where he chairs the Government Affairs Committee), the Computing Community Consortium Council, the Computer Science and Telecommunications Board of the National Research Council, and the DARPA Information Science and Technology Board (of which he is the vice chair).
Richard Lipton is a member of the National Academy of Engineering. His professional career has been primarily in academia. He held faculty appointments at Yale University, the University of California, Berkeley, and Princeton University before joining the faculty in the college of Computing at Georgia Tech. In addition to his computer science academic appointments, Lipton was the founding director of a computer science research laboratory for the Panasonic Corporation and is currently a chief consulting scientist at Telcordia (formerly known as Bellcore). Lipton’s research is focused primarily, but not exclusively, on theory. In a recent paper on the power of automata-based proof systems, he explored one way to address the NP = co-NP questions that considered the length of proofs of tautologies in various proof systems. In this joint work with A. Viglas he considered proof systems defined by appropriate classes of automata. Lipton found that in general, starting from a given class of automata, it was possible to define a corresponding proof system in a natural way. One new and more powerful proof system was based on the class of push-down automata. In this work, Lipton presented an exponential lower bound for oblivious read-once branching programs
that resulted in a proof system more powerful than oblivious regular resolution. He has also made important contributions in the areas of program testing, software engineering, and, most recently, DNA computing, combining molecular biology and computer science. It is generally acknowledged that Richard Lipton was one of the original pioneers in the field of DNA computing, along with Len Adleman.

Mitchel Resnick, a professor of Learning Research at the MIT Media Laboratory, develops new technologies to engage people (especially children) in creative learning experiences. His research group developed the “programmable bricks” that were the basis for the LEGO MindStorms robotics construction kits. Resnick co-founded the Computer Clubhouse project, an international network of after-school learning centers for youth from low-income communities. Resnick’s group recently developed a new programming language, called Scratch, which makes it easier for children to create their own interactive stories, games, and animations—and to share their creations on the Web. In the process, children learn to think creatively, reason systematically, and work collaboratively. He worked for 5 years as a science and technology journalist for Business Week magazine, and he has consulted around the world on the uses of new technologies in education. Resnick earned a B.S. in physics from Princeton University, and an M.S. and a Ph.D. in computer science from MIT.

Gerald Jay Sussman is the Panasonic (formerly Matsushita) Professor of Electrical Engineering at the Massachusetts Institute of Technology. Since 1964, he has worked on artificial intelligence research at MIT. He has also worked in computer languages and in computer architecture and VLSI design. Using the Digital Orrery he designed, Sussman has worked with Jack Wisdom to discover numerical evidence for chaotic motions in the outer planets. Sussman is coauthor (with Hal Abelson and Julie Sussman) of the introductory computer science textbook used at MIT from 1985 through 2007. The textbook (Harold Abelson, Gerald Jay Sussman, and Julie Sussman, 1985, Structure and Interpretation of Computer Programs, 1st edition, Cambridge, Mass., MIT Press) has been translated into French, German, Polish, Chinese, and Japanese. Sussman has pioneered the use of computational descriptions to communicate methodological ideas in teaching subjects in electrical circuits and in signals and systems. Over the past decade Sussman and Wisdom have developed a subject that uses computational techniques to communicate a deeper understanding of advanced classical mechanics. Computational algorithms are used to express the methods used in the analysis of dynamical phenomena. Expressing the methods in a computer language forces them to be unambiguous and computationally
effective. Sussman and Wisdom, with Meinhard Mayer, have produced a textbook, Structure and Interpretation of Classical Mechanics, to capture these ideas. Sussman is a fellow of the Institute of Electrical and Electronics Engineers. He is a member of the National Academy of Engineering and is also a fellow of the American Association for the Advancement of Science, the American Association for Artificial Intelligence, the Association for Computing Machinery (ACM), the American Academy of Arts and Sciences, and the New York Academy of Sciences.
