I am an assistant professor in the Department of Statistics, Rutgers University (New Brunswick, NJ). I was a postdoc working with Prof. Daniel Kuhn from EPFL and Prof. Andreas Krause from ETH Zurich. Before that, I got my PhD in Operations Research from the University of Illinois at Urbana-Champaign in 2022, advised by Prof. Xin Chen and Prof. Niao He.  I obtained Bachelor of Mathematics from Nankai University. 

My research interests lie in optimal decision-making under uncertainty, with an intersection of optimization, statistics, and machine learning. I study problems arising from reinforcement learning, alignment and fine-tuning of LLM, large-scale causal inference and discovery, and operations management, aiming to build new models and develop simple-to-implement methods with provable guarantees. See Research for details. I serve as an area chair for ICLR and a reviewer for journals like OR, MS, MP, SIAM OPT, MathOR, JASA, JMLR, as well as conferences like NeurIPS, ICML, ICLR, AISTATS, and COLT.

I am looking for motivated PhD students and research interns with backgrounds in mathematics, statistics, operations research, computer science, and other related fields. Feel free to send me an email if you find anything interesting. I am a skier, swimmer, hiker, and I play tennis.
