About Me

I am a 5th year PhD student in Mathematics at Princeton University. I am fortunate to get advised by Peter Constantin and Alexandru Ionecsu. My research interests primarily lie in partial differential equations arise in incompressible fluid dynamics. In particularly, my recent works focus on self-similar solutions of 2-D Euler.

I am seeking a postdoctoral position starting in Fall 2027.
