I am currently an Assistant Professor in Computer Science at IIT-Hyderabad. I received my Ph.D. in computer science from University of Edinburgh, advised by Myungjin Lee. Prior, I was a post doctoral researcher at Princeton University, USA, worked with Jennifer Rexford and David Walker.

I work at the intersection of Systems, Networks, and Security. My current focus is on designing and building networked systems that make networks easy to manage, secure, and robust, by using exciting emerging technologies such as Software-Defined Networking (SDN) and P4-based programmable data planes.

I am actively looking for full time candidates to work on some exciting research problems in the above areas for atleast one year. If you are interested, please apply by filling this form. We will screen the applications and get back to you.
