About Me

Hi! I am a PhD student in the GraphDeco group at INRIA Sophia-Antipolis with Dr. George Drettakis in the beautiful French Riviera. My research revolves around light transport theory; specifically, I am interested in using optimization-based methods to improve rendering algorithms. Check out my publications to learn more about my research.

I completed my Master’s at IIIT Hyderabad, where I was supervised by Dr. P. J. Narayanan and co-advised by Dr. Adrien Gruson and Dr. Luis Gamboa. I have previously worked as an intern at IBM Research and Metabrainz Foundation (GSoC 2020). Apart from my research interests, I love building well-designed, well-written, and helpful software systems. Take a look at the projects page to find projects I’ve worked on.

In my free time, I like to bike, run, and hike!
