Research Interests

Overall, I am interested in applied and computational math.
Currently, I work on numerical methods and applications of mean-field games and optimal transport.

Recent News

  • [2024.02] Our draft Zeroth-order Low-rank Hessian Estimation via Matrix Recovery is online. In this paper, we study how to estimate the Hessian matrix with less than O(n^2) function evaluation when the Hessian is approximately low-rank.

  • [2024.01] Our draft A Bilevel Optimization Method for Inverse Mean-Field Games is online. In this paper, we formulate the inverse mean-field game problem as a bilevel optimization problem and propose and implement an alternating gradient algorithm to solve it. We also study the model's unique identifiability and the algorithm's convergence.

  • [2023.03] I successfully passed my Ph.D. dissertation defense. I will join the math department at Duke University as a Phillip Griffiths Assistant Research Professor in fall 2023.
