Open Positions

• [Summer Research Intern] I'm looking for a summer research intern to work on a Bayesian optimization project. The candidate is expected to have solid background in mathematics and coding. Feel free to drop me an email if you are interested!

Research Interests

• Machine Learning: Bayesian optimization, bandit algorithms, active learning.

• AI for Drug Discovery: experimental design, drug screening, binding affinity prediction.

Teaching

• Fall 2025: CSI 501 Computational Algebra and Optimization [Syllabus]

• Spring 2025: CSI 436/536 Machine Learning [Syllabus]

• Fall 2024: CSI 436/536 Machine Learning

News

• May 2025: Paper "Bayesian Optimization with Inexact Acquisition: Is Random Grid Search Sufficient?" is accepted by UAI-2025 conference! In practice, exact acquisition function maximizer can be hardly obtained in Bayesian optimization, and our paper systematically studies this problem in theory. We find a condition under which the performance of GP-UCB and GP-TS can still be no-regret even without exact acquisition function maximization. Congrats to co-authors Hwanwoo Kim (Duke) and Yuxin Chen (UChicago)!

• Apr. 2025: Invited to be a session chair at INFORMS-2025. I'm co-organizing a session "Preference Learning in Large Language Models" together with Fan Yao (UNC). Happy to meet you in Atlanta in October!

• Jan. 2025: Paper "Constrained Multi-Objective Bayesian Optimization through Optimistic Constraints Estimation" is accepted by AISTATS-2025 conference! Many drug discovery problems are focusing on hitting multiple target performance criteria of a certain drug. In this paper, we model it as the constrained MOBO problem and solve it via optimistic constraints estimation. Congrats to co-authors Diantong Li (CUHK), Fengxue Zhang (UChicago), and Yuxin Chen (UChicago)!

• Jan. 2025: Happy to release a paper preprint "No-Regret Linear Bandits under Gap-Adjusted Misspecification"! This paper extends my UAI-2023 paper by proposing a new algorithm to relax a key assumption of it and providing a new gap dependent analysis.
