I joined the TensorFlow team at Google Brain in July 2018.

I received my Ph.D. in Computer Science from Princeton University, advised by Professor Michael J. Freedman. My research focuses on designing scalable, reliable, and highly-efficient distributed systems, which include topics on datacenter resource scheduling, big-data analytics, distributed machine learning, video stream processing, and in-network computing.

Previously, I interned at Facebook (summer 2017) and Microsoft Research (summer 2015). Before coming to Princeton, I received my B.Sc. in Computer Science from Peking University in 2013. I also received my B.A. in Economics (double major) from National School of Development.
