I'm an Applied Scientist at Microsoft AI. At Microsoft, I work on applied research problems in machine learning aimed at improving their advertising products. My research interests lie in general sequential decision making problems with a focus on the fundamental understanding and applications of interactive learning (reinforcement learning and bandits) and causal inference.
Before joining Microsoft, I finished my PhD at the Computer Science and Engineering department in University of Michigan, Ann Arbor. During my PhD, I worked on theoretical aspects of interactive learning and sequential decision making frameworks like reinforcement learning, bandits and (general) online learning. I was fortunate to be advised by Satinder Singh and Ambuj Tewari. My thesis developed provable sample efficient methods for reinforcement learning under various structural assumptions.
Before my stint in RL theory at UMich, I obtained my undergraduate degree in Computer Science from Indian Institute of Technology, Kanpur in May 2016.
