About

I am an incoming Ph.D. student in Computer Science at UMass Amherst CICS, advised by Prof. Marco Serafini. My research focuses on efficient systems for machine learning.

Before joining UMass Amherst, I received my M.S. in Computer Science from UC San Diego, where I worked with Prof. Yiying Zhang. I also worked with Prof. Hao Wang and Prof. Hong Zhang on Serverless Computing for AI. I received my B.E. from Huazhong University of Science and Technology and participated in an exchange program at Technical University of Munich.
