About:
I'm a final-year Ph.D. student at the Systems Lab and FOCI Center, University of Washington, advised by Arvind Krishnamurthy and Ratul Mahajan. I am also working closely with Danyang Zhuo.
Previously, I obtained my bachelor's degree (with honors) from the University of Michigan, where I was advised by Mosharaf Chowdhury at the SymbioticLab.
My research interests are broadly in systems and networking. My recent works focus on microservices, service mesh, and application networking. Currently, I lead the Application-Defined Networks (AppNet) project. Our vision is described in a paper presented at HotNets and a paper presented at HotOS.
