I am currently at Google. Previously, I was a senior research scientist and an engineering lead at Bytedance Inc in Seattle. My research interests include distributed machine learning and high performance networked systems.
I obtained my Ph.D. in computer science from UC Berkeley (2018) and my B.Eng. in computer science from Tsinghua University (2013).
