I am currently a forth year Ph.D. student at Princeton University, and I am fortunate to be advised by Prof. Sanjeev Arora.

I completed my undergraduate at Andrew Chi-Chih Yao’s CS pilot class at Tsinghua University, where I am advised by Prof. Wei Chen. Previously, I am also a reserach intern at Microsoft Research Asia Theory group and my mentor is Prof. Wei Chen. In my junior year, I also visited Duke University where I had a great time working with Prof. Rong Ge.

Research Interests

I am broadly interested in the intersection of algorithms and machine learning. Some particular interests include theory and applications for natual language processing (large language models), online leraning, optimization and federated learning.
