I am an assistant professor in the Department of Electrical and Computer Engineering at the University of California, Riverside. In 2023, I got my Ph.D. in Computer Sciences at the University of Wisconsin–Madison, where I was 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 work on interactive machine learning (e.g., active learning, bandits, and reinforcement learning), where my goal is to develop efficient human-in-the-loop learning algorithms and systems. Recently, I become increasingly interested in connecting interactive machine learning with large pre-trained models (e.g., large language models), from both algorithmic and systemic perspectives. Specifically, some of the research topics I would like to explore include:
How to align AI models with human intented goals (e.g., using reinforcement learning)?
How to design foundation model-powered interactive learning agents?
How to use interactive learning techniques to accerlarate model training/inference?
How to build testing and evaluation systems for large models?
\(\bigstar\) I am actively looking for Ph.D. students and visitors (in-person or remote). Please fill out this form if you are interested in working with me!
