I'm from Hangzhou, China. Currently in Los Angeles, USA. Passionate about mathematics and technology.


About Me

I am an Assistant Adjunct Professor for the Program in Computing at UCLA Department of Mathematics working with Professor Andrea Bertozzi. I completed my Ph.D. in Mathematics at Duke University under the guidance of Professor Thomas P. Witelski. I work on nonlinear partial differential equations, scientific computing, and data-driven mathematical modeling.

Here is my complete CV.
