I am an assistant professor in ECE/CSE departments at UC Riverside. In 2023, I got my Ph.D. in CS 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.
My research focuses on machine learning, reinforcement learning, and foundation models (e.g., LLMs), with an emphasis on developing efficient and reliable learning algorithms and systems for large-scale, multimodal problems. I am particularly interested in exploring the following research areas:
LLM-powered learning and decision making/RL agents
Efficient training and inference algorithms and systems
(Multimodal) Data selection, distillation, and generation
AI safety and alignment (e.g., using reinforcement learning)
Foundations of learning algorithms and foundation models
\(\bigstar\) Prospective Students. I am looking for multiple Ph.D. students (Fall 2025, fully-funded) and visitors/interns who are generally interested in ML/RL/LLM 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 your CV and transcripts.
