## ABOUT ME

(My name in Vietnamese: Từ Nguyễn Thái Sơn, people call me Tyson (Thai-Son).)

I am a Ph.D. student at the University of Wisconsin - Madison under the guidance of
Professor Hung V. Tran.
My dissertation is about Partial Differential Equations, particularly questions related to Hamilton-Jacobi equations.

I am interested in applied probability, statistics, machine learning and in using these skill sets to solve real world problems.
