About me

I am a fourth year Ph.D. student at UC Berkeley, jointly advised by Jiantao Jiao and Kannan Ramchandran. I am affiliated with the BLISS and BAIR labs.

I work on a variety of topics in machine learning with a focus on the statistical and computational aspects of adaptive decision making problems and reinforcement learning. I am also interested in nonconvex optimization and federated learning. I appreciate papers with well motivated theoretical formulations which either explain curious practical phenomena or ultimately provide intuitions missing in existing practical approaches.

I organize the BLISS seminar and CLIMB seminar at Berkeley. Shoot me an email if you are interested in giving a talk at either venue!

In a previous life, I was a dual degree student at the Department of Electrical Engineering, IIT Madras. I am fortunate to have had Ravishankar Krishnaswamy and Prof. Andrew Thangaraj as thesis advisors and work closely with Prof. Rahul Vaze.


1/23: I presented our recent work on nonlinear bandits at Google Research India and MSR India.

10/22: I will be participating in AIDS LifeCycle 2023. You can support me by clicking here. Every little bit counts!
