Tengyang Xie

I am a Postdoctoral Researcher at Microsoft Research New England (and New York City), affiliated with the NYC Machine Learning Group and MSR Reinforcement Learning Group. Starting in Fall 2024, I will be joining the University of Wisconsin-Madison as an Assistant Professor of Computer Science.

I received my Ph.D. in Computer Science at University of Illinois at Urbana-Champaign, where I was fortunate to work with Nan Jiang. I obtained bachelor's degree in Physics from University of Science and Technology of China. I have also spent time at Simons Institute, Amazon AI, Microsoft Research, and Google Research.

Research Interests: I work on Machine Learning. The primary goal of my research is to explore the mathematical principles and design efficient algorithms relevant to artificial general intelligence (AGI). My current interests include: 1) emerging interactive learning paradigms with/for large language models (LLMs), 2) the mathematical principles of reinforcement learning (RL) and decision-making, 3) applied machine learning for computer systems and physical science.

Prospective students. I am looking for self-motivated students. If you are interested in working or collaborating with me on topics related to LLM, RL, decision-making, ML/RL for X (or any aspect of AI/ML, broadly), please apply to our CS PhD program! If you are a current PhD/MS student at UW-Madison and interested in working with me, please reach out.
