About Me

In Fall 2018, I will join Department of Mathematics at UCLA as a Hedrick Assistant Professor.

I am interested in PDEs and numerical analysis arising in fluid dynamics in general. I am working with Prof. Fang-Hua Lin on PDEs in classic and complex fluids, and flow-structure interaction problems. I also worked with Prof. Michael Shelley on modeling and simulating active swimmers.

Here is my CV.


I will be teaching MATH 151A1/2 in Fall 2018.

MATH 151A1: MWF 9am.
  • Office hours: 1) TBA; or 2) by appointment.
  • Course TA(s): TBA.
MATH 151A2: MWF 10am.
  • Office hours: 1) TBA; or 2) by appointment.
  • Course TA(s): TBA.
