I am a fifth year PhD student at MIT CSAIL advised by Professor Daniel Sanchez and Professor Joel Emer. I work in computer architecture with a focus on accelerating irregular and sparse applications such as sparse transformers (GPT, Bert, etc.), sparse CNNs, sparse tensor algebra, and graph analytics.

Before joining MIT, I received a bachelor’s degree in Mathematics and Physics from Tsinghua University in 2019, where I worked with Professor Leibo Liu. I did a summer internship at UC Berkeley working with Professor Kurt Keutzer. I also had industry internship at Apple.
