About Me
I'm a J. L. Doob research assistant professor (postdoc) in the Dept. of Mathematics at the University of Illinois at Urbana-Champaign. I obtained my Ph.D degree in Mathematics at Purdue University in August 2019 under the supervision of Rodrigo Bañuelos. My Curriculum Vitae can be found here.

Research Interest
My research interests lie at the interface of probability and analysis. I am particularly interested in the study of functional and geometric inequalities, stochastic representation of singular integrals and Fourier multipliers, extremal problems for nonlocal operators, and Stein's method.
