Hi, welcome to my homepage. I am a Golomb Visiting Assistant Professor in Purdue University from 20162019, working with Dr. Samy Tindel. I obtained my PhD degree in the University of Kansas in 2016. My PhD advisors are Dr. David Nualart and Dr. Yaozhong Hu.
My research interest includes: Stochastic PDEs, Rough paths, Numerical approximations, Limit theorems, Nonlinear filtering, Statistics of random processes, and Malliavin calculus.
Here is my CV.
