I am an assoicate professor at the Institute for Interdisciplinary Information Sciences of Tsinghua University in Beijing.

I have a broad research interest in distributed system design, big data and financial technology. My current projects include privacy-preserving computation, data center networking, large scale system for machine learning and data mining, as well as various big data applications.

I received my Ph.D from UC Berkeley in 2010. I was a member of RAD Lab in EECS Department. My advisors are Prof. David Patterson and Prof. Armando Fox. My dissertation is on analyzing free text console logs for problem detection. I worked for Google for 2.5 years as a software engineer before joining Tsinghua.

My Google Scholar Page tracks more recent publications, and may be more up-to-date than this pape.
