About Me

  • Ph.D in Mathematics, Purdue University, 2016 - Current. Advisers: Harsha Honnappa and Ben McReynolds.

  • B.S. in Mathematics with Minor in Physics, University of California at Davis, 2014.

My research interests are in probability theory and its applications. In particular, I am interested in stochastic differential equations, rough paths theory, Malliavin calculus, large deviations theory, Gaussian measure theory and stochastic control. I am a member of Stochastic Systems Lab led by Harsha Honnappa.
