Professor of Mathematics, University of Virginia.

Leonid Petrov works in integrable probability, an area of mathematical research at the interface between probability / statistical physics on the one hand and representation theory/quantum integrability on the other. He applies tools from integrability (symmetric functions and Yang-Baxter equations for solvable lattice models) to analyze the asymptotic behavior of stochastic models motivated by a wide range of real-world questions, including the structure of ice and other condensed matter, magnetism, quantum spin systems, thermodynamics, traffic models, and directed polymers.

Petrov completed his Ph.D. in 2010 in Moscow with advisor Grigori Olshanski. Following a postdoctoral position at Northeastern University (2011-2014), he joined the University of Virginia as faculty in Department of Mathematics. He has held visiting positions at MIT (2017-2018), MSRI (Fall 2021), and IPAM (Spring 2024).

Recently, he is also involved in broadening access to AI tools for working mathematicians by sharing best practices, participating in panel discussions, and utilizing AI to build interactive simulations of cutting-edge research advances in integrable probability and beyond (see below for a few comprehensive examples).
