I am an Assistant Professor in Computer Science and Engineering at the University of California, San Diego. I am primarily interested in operating systems and networks in datacenters. My recent research focuses on improving the efficiency of datacenter applications.

Prior to UCSD, I was a postdoctoral researcher in the NetSys Lab at UC Berkeley, where I worked with Scott Shenker and Sylvia Ratnasamy. I received my Ph.D. in 2019 from MIT CSAIL, advised by Hari Balakrishnan and Adam Belay, and I received a B.S.E. in Computer Science from Princeton University.

I am looking for students! If you are interested in working with me, please apply to UCSD and mention my name in your application. Feel free to email me as well.
