I am a final-year Ph.D. student in Computer Sciences at the University of Wisconsin–Madison, where I am fortunate to be advised by Robert Nowak. In 2021, I spent a wonderful summer at Microsoft Research NYC, working with Paul Mineiro, Dylan Foster, and John Langford.

I am on the 2022–2023 job market.

I work on interactive machine learning, where I develop efficient human-in-the-loop learning algorithms and systems to speed up the learning and training process. I build algorithmic, statistical, and computational foundations for active learning, bandits, reinforcement learning, and best action identification, and I pay particular attention to connecting deep learning and systems with these interactive learning paradigms. My research has been incorporated into leading ML libraries and commercial products. I also actively participate in interdisciplinary collaborations and use my expertise to help scientists in other domains.
