About Me

I'm a Ph.D. Candidate in Machine Learning at Georgia Tech, advised by Prof. Juba Ziani. Before Georgia Tech, I completed my M.S. and B.S in Computer Science at ENS de Lyon and BITS-Pilani Goa.

I'm passionate about Trustworthy ML: algorithms that preserve privacy, are fair to subpopulations and make good sequential decisions. My research is in Differential privacy(DP), Fairness and Recommender systems.

I have industry experience as an Applied Science intern with Amazon in the Personalized recommendations team, and as a Machine learning intern at Keysight in the AI explainability team.

In my free time, I enjoy hiking, climbing 🧗 and board games.
