Donald Greenberg, the former Jacob Gould Schurman Professor of Computer Graphics, researched and taught in the field of computer graphics from 1966 to 2025. During the last 15 years, he was primarily concerned with research advancing the state-of-the-art in computer graphics and with utilizing these techniques as they may be applied to a variety of disciplines. His specialties include real-time, realistic image generation, color science, and computer-aided architectural design. He taught the computer graphics courses in Computer Science, computer-aided design for the Department of Architecture, computer animation for the Department of Art, and technology strategy in the Business School. He received his B.C.E. from Cornell in 1958 and his Ph.D. in 1968. Greenberg also studied at Columbia University.

James Grimmelmann is the Tessler Family Professor of Digital and Information Law at Cornell Tech and Cornell Law School. He studies how laws regulating software affect freedom, wealth, and power. He helps lawyers and technologists understand each other, applying ideas from computer science to problems in law and vice versa.

Giulia Guidi is an assistant professor in the Department of Computer Science at Cornell University. She received her Ph.D. in computer science from UC Berkeley. Guidi works in the field of high-performance computing (HPC) for large-scale computational sciences and leads the Cornell HPC group. She is interested in developing algorithms and software infrastructures on parallel machines to speed up data processing without sacrificing programming productivity, and to make high-performance computing more accessible. She is also a big fan of sparse linear algebra and believed in sparse linear algebra as a computational abstraction for tackling large-scale computational challenges.

François Guimbretière is a professor of information science. Guimbretière's research explores how hardware/software co-design can deliver novel interactions in a broad set of application domains. Blending system building and design, Guimbretière and his students strive to turn future visions of seamless interactions into today’s reality. His prior work explored pen-based interfaces on paper and screen. He currently focuses on novel fabrication techniques, such as interactive printing and yarn-based fabrication. He is also interested in the intersection of HRI and sustainability, including the design of immersive and engaging remote collaboration interfaces that limit our reliance on physical travel.

In Memoriam: Joe Halpern, ‘towering’ computer scientist and mentor, dies at 72

Bharath Hariharan is an associate professor in computer science. He works on computer vision and machine learning, specifically, on important problems that defy the "Big Data" label. He enjoys problems that require marrying advances in machine learning with insights from computer vision, geometry, and domain-specific knowledge. A few of the research problems his group works on include recognition for satellite images and earth science and 4D reconstruction and recognition. An exhaustive list of publications is available on Google scholar. His work has been recognized with an NSF CAREER award and a PAMI Young Researcher Award. 

Kyle Harms teaches courses emphasizing programming and human-computer interaction, often with web technologies. He primarily focuses on classroom innovation at scale. His pedagogical approach incorporates active learning methods, motivating students with personal projects, and carefully integrating generative AI into the classroom.

Haym Hirsh is a professor in the Department of Computer Science at Cornell University. His research has focused on foundations and applications of machine learning, data mining, information retrieval, and artificial intelligence, especially targeting questions that integrally involve both people and computing. Most recently these interests have turned to crowdsourcing, human computation, and collective intelligence. Haym received his B.S. from the Mathematics and Computer Science Departments at the University of California, Los Angeles, and his M.S. and Ph.D. from the Computer Science Department at Stanford University. Prior to moving to Cornell in 2013 to serve as dean of the Faculty of Computing and Information Science, Hirsh spent 24 years on the computer science faculty at Rutgers University, and has had visiting positions at AT&T Labs, Bar-Ilan University, Carnegie Mellon University, MIT, and the University of Zurich. From 2006-2010 he served as director of the Division of Information and Intelligent Systems at the National Science Foundation. In 2022 he was elected a Fellow of the American Association for the Advancement of Science. 
 

I develop and apply statistical methods to explain political and social phenomena. My work focuses on the social effects of government policies, on how small groups of people adapt to sudden changes in their lives, and on low-dimensional representation of social interaction and language. Most of the applications are in American politics, public policy, and health care.

Dr. Guy Hoffman is an Associate Professor and the Mills Family Faculty Fellow in the Sibley School of Mechanical and Aerospace Engineering at Cornell University. Prior to that he was an Assistant Professor at IDC Herzliya and co-director of the IDC Media Innovation Lab. Hoffman heads the Human-Robot Collaboration and Companionship (HRC²) group, studying the algorithms, interaction patterns, and designs enabling the co-existence of people and robots in the workplace and at home. 



 

Yongmiao Hong is the Ernest S. Liu Professor of Economics and International Studies Emeritus.
 

John E. Hopcroft is Professor Emeritus in Computer Science at Cornell University. From January 1994 until June 2001, he was the Joseph Silbert Dean of Engineering. After receiving both his M.S. (1962) and Ph.D. (1964) in electrical engineering from Stanford University, he spent three years on the faculty of Princeton University. He joined the Cornell faculty in 1967, was named professor in 1972 and the Joseph C. Ford Professor of Computer Science in 1985. He served as chairman of the Department of Computer Science from 1987 to 1992 and was the associate dean for college affairs in 1993. An undergraduate alumnus of Seattle University, Hopcroft was honored with a Doctor of Humanities Degree, Honoris Causa, in 1990.

Henry's research interest include statistics, image science, bioinformatics, data science, machine learning, artificial intelligence, biomedical studies, and industrial applications.
 

Justin Hsu is an associate professor of computer science. Previously, he was an assistant professor in the Department of Computer Sciences at the University of Wisconsin–Madison, and a postdoc in the Department of Computer Science at Cornell University and in the Programming Principles, Logic, and Verification Group at the University College London. He obtained his Ph.D. from the Department of Computer Science at the University of Pennsylvania. 

Lee Humphreys is an Assistant Professor in the Department of Communication at Cornell University. She is interested in the social uses and perceived effects of communication technology. Her research has explored mobile phone use in public spaces and emerging norms on mobile social networks both in the US and in Indonesia. Using qualitative field methods, she focuses on how people integrate communication technology in their everyday lives in order to facilitate identity management and social interaction. Her work also explores how people perceive privacy and surveillance issues around mobile social media. 

Professor Hwang is also a Professor Emeritus in the Department of Mathematics.
