Hadar Averbuch-Elor is an assistant professor of computer science at Cornell Tech and the Cornell Ann S. Bowers College of Computing and Information Science. Averbuch-Elor’s research interests lie in the intersection of computer graphics and computer vision, particularly in combining pixels with more structured modalities, such as natural language and 3D geometry.

Shiri Azenkot is an associate professor of information science at Cornell Tech, the Cornell Ann S. Bowers College of Computing and Information Science, the Jacobs Technion-Cornell Institute, and the Technion-Israel Institute of Technology.

Kavita Bala is the 17th provost of Cornell University and professor of computer science. Previously, she served as the inaugural dean of the Cornell Ann S. Bowers College of Computing and Information Science and chair of the Department of Computer Science. In her research, she specializes in computer vision and computer graphics, leading research in visual recognition and search; and material modeling and perception. She co-founded GrokStyle, a visual recognition AI company that drew IKEA as a client, and was acquired by Facebook in 2019. Bala is a Fellow of the American Academy of Arts & Sciences (2025), an Association for Computing Machinery (ACM) Fellow (2019), Fellow of the SIGGRAPH Academy (2020), and recipient of the Computer Graphics Achievement Award (2020).

Tapomayukh "Tapo" Bhattacharjee is an assistant professor in the Department of Computer Science at Cornell University where he directs the EmPRISE Lab. He completed his Ph.D. in robotics from Georgia Institute of Technology and was an NIH Ruth L. Kirschstein NRSA postdoctoral research associate in Computer Science and Engineering at the University of Washington. He wants to enable robots to assist people with mobility limitations with activities of daily living. His work spans the fields of human-robot interaction, haptic perception, and robot manipulation and focuses on addressing the fundamental research question of how to leverage robot-world physical interactions in unstructured human environments to perform relevant activities of daily living. 

David S. Bindel is a professor of computer science and director of the Center for Applied Math. He works at the interface of computational science and engineering, and his research mixes mathematical analysis, application modeling, and software design. Active research areas include: optimizing stellarators, verified numerics, kernel methods, parallel surrogate optimization, spectral network analysis, nonlinear eigenvalue bounds, and nonlinear waves in resonant MEMS. Bindel received his Ph.D. in computer science from the University of California, Berkeley and his B.S. in math and computer science from the University of Maryland, College Park. He is a SIAM Fellow and Sloan Fellow.

Ken Birman is the N. Rama Rao Professor of Computer Science. His research is on reliable, secure, and scalable distributed systems. Current projects include Vortex, a platform for speeding up AI and ML inference or knowledge retrieval tasks by fully leveraging cutting edge hardware accelerators and reimplementing key data paths to reduce or eliminate copying and other delays; Cascade, an exceptionally performant storage framework for Vortex; and Derecho, a highly optimized library for accelerating communication that leverages RDMA when available. Jointly, these three elements enable dramatic improvements in the cost of ML hosting and sharp reductions in ML latencies. In more entrepreneurial roles, Ken founded a series of companies. One focused on software fault tolerance and created a variety of cloud computing infrastructure solutions. Another architected and implemented the core of the New York Stock Exchange trading floor, the Swiss Exchange, the French Air Traffic Control System communication platform, and created a secure, high-speed data sharing capability for the U.S. Navy AEGIS warship. Ken received his Ph.D. and master's degrees in computer science from the University of California, Berkeley and his B.A. in computer science from Columbia University, is an ACM Fellow and IEEE Fellow, and won the IEEE Tsutomo Kanai award for his innovations in distributed computing.

Florentina Bunea is a professor of statistics and data science and a member of the graduate fields of statistics, applied mathematics, and computer science. Her research is broadly centered on statistical machine learning theory and high-dimensional statistical inference. She is interested in developing new methodology accompanied by sharp theory for solving a variety of problems in data science and in the growing area of AI output evaluation. She continues to be interested in the general areas of mixture modeling, latent space estimation, sparsity and dimension reduction in high dimensions, and statistical optimal transport, as well as their applications, most recently to large language models and immunology, among others. Specific research foci include:

Claire Cardie is the John C. Ford Professor of Engineering in the Departments of Computer Science and Information Science. She was the founding chair of the Department of Information Science and led the development of its academic programs. Cardie works in the area of Natural Language Processing (NLP) on topics ranging from information extraction, text summarization, and noun phrase coreference resolution, to the automatic analysis of opinions, argumentation, and deception in text. 

Eshan Chattopadhyay is currently an associate professor (with tenure) in the Department of Computer Science at Cornell University. He joined Cornell in 2018 after completing postdoctoral work at the Institute for Advanced Study in Princeton and the Simons Institute for the Theory of Computing in Berkeley.
