I am a fourth-year Ph.D. student in Computer Science at the University of Washington working with Kevin Jamieson. My research interests are in active learning, reinforcement learning, and control theory. I am 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.
