I am a first-year PhD student advised by Prof. Henry Lam and Prof. Adam Block. My research lies at the intersection of applied probability and statistics, control, and (stochastic) differential equations. Recently I have been working on diffusion models for rare events, from classical rare-event problems to biomolecular systems, and on watermarking for large language models.

I received my B.S. in Mathematics and Applied Mathematics from Fudan University. During my undergraduate studies, I was fortunate to be advised by Prof. Yiping Lu and Prof. Kaizheng Wang. I am also deeply grateful to Prof. Yingzhou Li for his generous guidance and support throughout my academic journey.
