Research

My research sits at the intersection of operations research, reinforcement learning, and stochastic systems. I focus on designing algorithms with theoretical structure and evaluating them in realistic simulation environments.

Sequential Decision Making

Modeling and solving sequential problems under uncertainty using dynamic programming, approximate dynamic programming, MDPs, and SMDPs.
