I am a sixth-year PhD student in Computer Science at the University of Washington working with Kevin Jamieson. I have also spent time at Microsoft Research, mentored by Dylan Foster, as well as the Simons Institute, and my work has been supported by an NSF Graduate Research Fellowship. Previously, I completed a master's and bachelor's degree at the University of Michigan, both in Electrical Engineering. While at the University of Michigan, I worked with Raj Rao Nadakuditi and Necmiye Ozay.
My research centers on developing learning-based algorithms for decision-making in sequential environments. In particular, much of my work has focused on obtaining better-than-worst-case guarantees for reinforcement learning and learning in dynamical systems, and algorithms which provably adapt to the difficulty of, and perform optimally on, each particular problem instance.
