About
I am an Assistant Professor in the Department of Computer Sciences at the University of Wisconsin Madison. I am a member of machine learning@uw-madison and a faculty affiliate with the Data Science Institute. Previously I was as a postdoc researcher in the Computer Science department at Stanford University, working with Christopher RĂ©.
I completed my PhD from Cornell University in 2017, where I was fortunate to be advised by John E. Hopcroft.
My research focuses on algorithmic and theoretical foundations of safe and reliable AI, addressing challenges in both model development and deployment in the open world. This involves handling out-of-distribution data, quantifying uncertainty and learning novel structures and categories therein. Currently, our emphasis is on building responsible foundation models, such as large language models and vision-language models. We are driven to deeply understand how they work, when they fail, and effectively align them with human needs and desires.
[Openings]: I am looking for creative and curiosity-driven minds to join my lab, with fully funded positions. The admission decision at UW-Madison is committee-based. For questions regarding the application process, please see the FAQ. I highly recommend reading my [Advising Statement] before you apply or email me.
