Jing Wang and Partha Dey are now organizing the probability seminar.
I organized an MSRI semester in fall 2015: PDE, dynamics, and randomness in high dimensions


Math 564 Applied Stochastic Processes, Fall 2016
Math 461 Probability Theory, Spring 2015
Math 564 Applied Stochastic Processes, Fall 2014


Interests: Statistical mechanics, differential equations, and quantum theory. General description of some of my results and aims. What's new: I'm learning machine learning.
Scaling limits are fundamental to my research. Specifically, I'm interested in:

Other Interests

I've mentored Illinois Geometry Lab projects on percolation theory with Michelle Delcourt and Thomas Mahoney, and a project on phase transitions in XY models with Tayyab Nawaz.

My NSF CAREER Award has been providing partial support for Urbana's Kovalevsky Days.
