I am a PhD student in the Machine Learning Department at Carnegie Mellon University, where I am advised by Steven Wu. My research centers around privacy-preserving machine learning and uncertainty quantification. Previously, while completing my master's degree (also from CMU), I worked on multimodal machine learning and federated learning under Louis-Philippe Morency. Before that, I obtained my bachelor's degree in math and economics from the University of Chicago.
My work has been supported by the Bloomberg Data Science Ph.D. Fellowship (link).
