I am working on a stealth startup after I briefly worked at Google. Before Google, I was a Director at ByteDance, responsible for the company's AI infrastracture. I started my career as a Researcher at Microsoft Research.

My interests include distributed systems and networks. I enjoy building large-scale software systems with emerging hardware like GPU, RDMA NICs and programmable ASICs.

I obtained my Ph.D. from the Department of Computer Science at UCSB, co-advised by Prof. Ben Y. Zhao and Prof. Heather Zheng. I received my bachelor degree from Tsinghua University.

I am a recipient of Microsoft Research Ph.D. Fellowship (2015).
