about

I am a Miller Postdoctoral Fellow at UC Berkeley, hosted by Shafi Goldwasser. Prior to this, I completed my Ph.D. in the Stanford Theory Group under the sage guidance of Omer Reingold.

My research investigates foundational questions about responsible machine learning. Much of my work aims to identify ways in which machine-learned predictors can exhibit problematic behavior (e.g., unfair discrimination) and develop algorithmic tools that provably mitigate such behaviors. More broadly, I am interested in how the computational lens (i.e., algorithms and complexity theory) can provide insight into emerging societal and scientific challenges.
