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 became interested in connecting interactive machine learning with large models (e.g., large language models), from both algorithmic and systemic perspectives. Specifically, some research topics I would like to further explore include:

• Data selection and generation for large models

• LLM-powered interactive learning agents and systems

• Efficient training and inference systems for large models

• AI safety and alignment (e.g., using reinforcement learning)

• Theoretical foundations of interactive ML/transformer/attention

\(\bigstar\) Prospective Students. I am actively looking for Ph.D. students (Fall 2024/Spring 2025, fully-funded) and short-term visitors/interns who are generally interested in AI/ML and/or ML Systems. I'm happy to work with students with CS/ECE/Math/Stat/Physics or other STEM backgrounds. If you are interested in joining my lab, please (i) fill out this form and (ii) drop me an email with you CV and transcripts.
