I am an Associate professor at the University of Birmingham, School of Mathematics. Previously, I held research positions at the University of Edinburgh (where I worked with Tadahiro Oh), and Memorial University (where I worked with Jie Xiao). I received my PhD from Peking University under the supervision of Carlos Kenig and Baoxiang Wang.

Curriculum Vitae: CV


Research Interest: Analysis group at UoB

Nonlinear Partial Differential Equations and Harmonic Analysis. In particular, the study of nonlinear dispersive PDEs such as nonlinear Schrödinger equations, nonlinear wave equations, and the KdV equation by using techniques from PDEs, Harmonic Analysis, and Probability theory. Mainly, well-posedness (existence, uniqueness, and stability of solutions) in both deterministic and probabilistic settings, existence of invariant measures, Strichartz estimates in different settings, etc. Also, interested in Fourier restriction theory and \(\ell^2\) decoupling theory.
