About Me

I am a Hedrick Assistant Adjunct Professor at Department of Mathematics, UCLA. I am working with Prof. Inwon Kim.

Research Interests: PDEs and applied mathematics, especially fluid-structure interaction problems, evolution free boundary problems, Navier-Stokes equations, liquid crystals, and complex and active fluids.

Here is my CV.
