Yuejie Chi is the Charles C. and Dorothea S. Dilley Professor of Statistics and Data Science at Yale University, with a secondary appointment in Computer Science. She is a member of the Yale Institute for Foundations of Data Science. Previously, she held the Sense of Wonder Group Endowed Professor position at Carnegie Mellon University with affiliations in the Machine Learning Department (MLD) and CyLab. Her career includes a visiting researcher position at Meta's Fundamental AI Research (FAIR) group. Dr. Chi received her Ph.D. and M.A. in Electrical Engineering from Princeton University in 2012 and 2009, respectively, and her B.E. (Hon.) in Electrical Engineering from Tsinghua University, Beijing, China, in 2007. Her educational background laid the foundation for her interdisciplinary research approach spanning statistics, computer science, and engineering domains. Professor Chi's research focuses on the theoretical and algorithmic foundations of data science, with particular emphasis on generative AI, reinforcement learning, and signal processing. Her work lies at the intersection of statistics, learning, optimization, and sensing, addressing fundamental challenges in improving the performance, efficiency, and reliability of AI systems in data-intensive but resource-constrained scenarios. Her group's research is highly interdisciplinary, tackling problems that require theoretical rigor alongside practical implementation considerations. Theoretical foundations of generative models and diffusion processes Algorithmic guarantees for reinforcement learning systems Robust and efficient optimization methods for large-scale problems Low-dimensional structures in high-dimensional data Professor Chi's recent publications reveal a strong trajectory toward addressing fundamental theoretical questions in AI while maintaining practical relevance. Her work demonstrates increasing focus on the interplay between theoretical guarantees and practical implementation, particularly in generative models and reinforcement learning systems. Notable themes include non-asymptotic convergence analysis, robustness guarantees, communication efficiency in distributed settings, and bridging theoretical insights with real-world applications. Among her distinguished recognitions are the Presidential Early Career Award for Scientists and Engineers (PECASE) from the White House, the inaugural IEEE Signal Processing Society Early Career Technical Achievement Award, the SIAM Activity Group on Imaging Science Best Paper Prize, and the IEEE Signal Processing Society Young Author Best Paper Award. She is an IEEE Fellow (Class of 2023) for contributions to statistical signal processing with low-dimensional structures. Additional honors include young investigator awards from NSF, ONR, and AFOSR, and she has been named a Goldsmith Lecturer by IEEE Information Theory Society (2021), a Distinguished Lecturer by IEEE Signal Processing Society (2022-2023), and a Distinguished Speaker by ACM (2023-2026). Professor Chi has mentored an impressive cohort of PhD students and postdoctoral researchers, many of whom have received prestigious fellowships and awards. Her advisees have secured positions at leading institutions including Johns Hopkins University, MIT, UNC Chapel Hill, and major technology companies like Meta, Apple, and Google. Her group has produced numerous award-winning papers and dissertations, including the IEEE SPS Best PhD Dissertation Award. She has successfully secured significant research funding from federal agencies and industry partners to support her interdisciplinary research program. Professor Chi leads a vibrant research group at Yale that maintains active collaborations across multiple disciplines and institutions. Her group's work spans theoretical analysis, algorithm development, and practical implementation, with emphasis on both foundational understanding and real-world applicability. The group has developed several influential frameworks including Robust Gymnasium, a unified modular benchmark for robust reinforcement learning, and has made significant contributions to understanding the theoretical properties of modern AI systems.
