I am an Assistant Professor of Computer Science at Johns
Hopkins University, where I lead the Order Lab. My research
spans broadly in systems including OS and distributed systems. I am particularly
interested in the research of building reliable, efficient, and defensible systems
in data centers, mobile phones and IoT devices.
I’m looking for motivated graduate students and undergraduate interns who are
interested in systems building and research. Prospective
students please read this.

I received my Ph.D. from UCSD, advised by
Prof. Yuanyuan Zhou. Before joining Hopkins,
I took one year off at MSR Redmond Systems Group
to gain exposure to real-world system challenges in a state-of-the-art cloud service, Microsoft
Azure. I received B.S. (Computer Science) and B.A. (Economics) from Peking University.
