I am a Mathematics major at Princeton University, expected to graduate on May 2021.

I have been excited about Artificial Intelligence since middle school. My first project was a chess engine written in C++. Now, I use PyTorch to reimplement papers and conduct research. My main interests are Computer Vision and Reinforcement Learning.

When I am not working, I enjoy playing Table Tennis and Badminton.
