I am currently a first year Ph.D. at Princeton University.

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 theoretical computer science and theoretical machine learning. Some particular interests include deep learning theory, optimization and federated learning, online algorithms and online leraning.
