I'm a Graduate Student at University of Illinois at Urbana-Champaign where I'm co-advised by Prof. Radhika Mittal and Prof. Brighten Godfrey.

Previously, I was a Research Fellow at Microsoft Research India, where I worked with Dr. Venkat Padmanabhan, Dr. Nagarajan Natarajan, Dr. Sundararajan Sellamanickam and Dr. Johannes Gehrke on networking research in the context of global-scale online services.

Prior to my time in research, I spent 6 months working for Mozilla on Network Security Services as part of Mozilla Winter of Security. I graduated with a B.Tech in Computer Science and Engineering from National Institute of Technology, Trichy, India in 2018.

I am quite broadly interested in Systems and Networking. In recent times, my focus has been on Service Meshes and Microservices.
