The Scientist

I successfully defended my PhD at Northeastern University , under the advisement of Javed Aslam.

I am a researcher with expertise in multi-armed bandits and general machine learning. I am particularly interested in working in fields like recommender systems, personalization and advertisement. I also have an interest in speeding up training algorithms under budget (or time) constraints. For my PhD thesis, I developed bandit model algorithms for exploring and choosing good options when you have unlimited possibilities. I was the first to prove upper and lower bounds on the budget needed to find one of the top few of unlimited options, and my fixed-budget algorithm takes a surprising approach that empirically matches or outperforms all state-of-the-art algorithms. I have worked on applications like training greedy optimal boosted decision trees faster and finding the optimal dose in cancer clinical trials. I am also interested in pivoting to nearby fields, such as reinforcement learning.

Current project: I am currently wrapping up some work in the pure exploration setting of the infinitely-armed bandits in the fixed budget setting. This work is in collaboration with Kevin Jamieson and Javed Aslam.
