About Me

I am a first-year PhD student in Computer Science at UMass Amherst advised by Bruno Castro da Silva and Phil Thomas at the Autonomous Learning Lab. I received my master’s degree at Carnegie Mellon University from the Electrical and Computer Engineering Department. I completed my undergraduate studies from the Department of Electrical Engineering at the Indian Institute of Technology Madras.

My research interests lie broadly in the field of reinforcement learning and various machine and deep learning tools and concepts. I have also worked on various related areas like natural language processing and multi-armed bandits amongst others, details about which can be found in the Projects section. My interests motivated me to acquire industrial experience in autonomous-driving and financial sectors through internships at Uber ATG and Goldman Sachs respectively.

In my free time, I love to read, run and play soccer. As an undergraduate student, I was a member of the institute athletics team at IIT Madras.
