About

Welcome to my homepage!

I am a senior machine learning researcher on the Apple Foundation Models pre-training team. I received my Ph.D. degree in Computer Science from Cornell University, advised by Chris De Sa. I’m also grateful to work with Vitaly Shmatikov on machine learning privacy. Prior to Cornell, I obtained bachelor degree in Mathematics (ZhiYuan Honors) from Shanghai Jiao Tong University, where I am fourtunate to be advised by John E. Hopcroft and Huan Long.

My work spans efficient model architectures, accurate scaling, and low-precision training. I am also interested in building efficient machine learning systems for large-scale foundation models, my goal is to make foundation models more capable and efficient.
