About


Hi! I am currently a postdoc researcher at CMU and Harvard working with Prof. Vyas Sekar and Prof. Minlan Yu. I obtained my PhD degree in 2018 from Department of Computer Science at Johns Hopkins University, where I was advised by Prof. Vladimir Braverman.

My research interests include systems and algorithms in networked and distributed settings. In particular, I work on efficient algorithmic and systematic design for SDNs, Datacenters, Programmable Networks, and "big data" Systems.
