I'm a post-doc at the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT, with Professors Hari Balakrishnan and Mohammad Alizadeh. I got my PhD at Princeton University, advised by Prof. Jennifer Rexford. I also worked closely with Prof. David Walker. I received a B.Tech in Computer Science from Indian Institute of Technology Madras in 2010.

My research aims to make computer networks easy to manage. I design networks that can be flexibly programmed to allow network operators and designers to understand the network's operation and implement novel functions. Programmability enables network operators to diagnose poor application performance, allocate resources more efficiently, and secure the network better. To achieve these goals, I have combined by primary expertise in Computer Networking with principles from Programming Languages, Computer Architecture, and Algorithms. My Ph.D. dissertation is entitled "Declarative Network Path Queries," focussing on measuring traffic accurately. I have since worked on fine-grained performance monitoring and congestion control.
