Teaching

  Here are some of the previous courses I have taught

Teaching in Spring 2022


Math635, Introduction to Brownian motion and stochastic calculus
MWF 9:55AM - 10:45AM (Van Vleck B123)

TEXTBOOK: Steele, Stochastic Calculus and Financial Applications
Grader: TBA
The course grade is based on homework assignments, one midterm, and a cumulative final exam.


Research

I am interested in stochastic partial differential equations, and its interaction with quantum field theory, statistical mechanics, interacting particle systems and geometric flows.
