About me

I am a fourth-year Ph.D. student affiliated with Division of Decision and Control Systems (DCS) at KTH Royal Institute of Technology. I am fortunate to jointly work with Prof. Karl H. Johansson at KTH and Prof. Michael M. Zavlanos at Duke University. Before that, I received both the master and bachelor degrees at Honors School of Harbin Institute of Technology.

I am currently visiting Learning & Adaptive Systems Group at ETH Zurich, hosted by Prof. Andreas Krause. Look forward to the discussions and meetings in Zurich!

Research

I am broadly interested in the intersection of control, machine learning, optimal transport, and game theory. I have worked on research topics including distributionally robust optimization, CVaR optimization, distributional reinforcement learning in LQR, decision-dependent optimization. Lately, I have been exploring generative models with a special focus on flow matching models.
