Welcome to my homepage! I am a postdoctoral research associate at the Machine Learning Department (MLD) of Carnegie Mellon University (CMU), working with Prof. Aarti Singh and Prof. Bryan Wilder. Before joining CMU, I got my PhD in Computer Science at UC Santa Barbara in 2024, advised by Prof. Yu-Xiang Wang. Even before that, I got my B.S. from Tsinghua University in 2019, advised by Prof. Guoqi Li.

    My current research interest lies in Generative Online Learning. Specifically, I develop provable methodologies to actively generate new actions while simultaneously learning from existing ones. Beyond the traditional balance of exploration and exploitation, my works introduce a third dimension –creation– by integrating generative AI into real-time decision-making. On the application side, I am leading a project of developing a maternal health chatbot system that generates healthcare content under autonomous guardrails.

    During my PhD (and ongoing), I have been doing a series of work on dynamic pricing. Besides, I also worked on graph theory and combinatorics out of personal interests.

    I am currently on the 2025–26 job market, and welcome opportunities for academic and industrial research positions. Please check my CV here for more details.
