I am at an early-stage startup called Forward Networks in Palo Alto, CA. In the past, I have worked/interned at Google, NetLogic Microsystems (now Broadcom), and Intel.
I received my PhD in Computer Science in 2014 at University of California, San Diego where I worked in the Systems and Networking Group advised by Prof. Amin Vahdat. My dissertation was titled Network Performance Improvements For Web Services – An End-to-End View.
My research interests include data center networks, distributed systems, operating systems, and computer networks.
Prior to my PhD, I got my MS in Computer Science in 2010 at University of California, San Diego, and my B.Tech. in Computer Science and Engineering in 2008 at IIT Madras, India.
