Khanin’s research covers a broad range of topics, and his academic career is similarly extensive having held positions around the globe. He completed his PhD in Mathematical Physics from the L.D. Landau Institute for Theoretical Physics in Moscow, where he served as a Research Associate until 1994. He held visiting appointments at a range of institutes in various countries including Italy, Switzerland, the US, Israel, France and Japan. After serving in academic positions at Princeton University, the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge, and the Heriot-Watt University in Edinburgh, Khanin joined U of T Mississauga in 2005. He was the Chair of MCS from 2008-13. His research interests currently include dynamical systems, probability theory, statistical mechanics, turbulence theory and mathematical physics.

On Dynamics of Lagrangian Trajectories for Hamilton–Jacobi Equations
Archive for Rational Mechanics and Analysis


Characteristic curves of a Hamilton–Jacobi equation can be seen as action minimizing trajectories of fluid particles. However this description is valid only for smooth solutions. For nonsmooth “viscosity” solutions, which give rise to discontinuous velocity fields, this picture holds only up to the moment when trajectories hit a shock and cease to minimize the Lagrangian action.

The intermediate disorder regime for directed polymers in dimension 1 + 1
The Annals of Probability


We introduce a new disorder regime for directed polymers in dimension 1+11+1 that sits between the weak and strong disorder regimes. We call it the intermediate disorder regime.

The Continuum Directed Random Polymer
Journal of Statistical Physics


Motivated by discrete directed polymers in one space and one time dimension, we construct a continuum directed random polymer that is modeled by a continuous path interacting with a space-time white noise.

Space-time stationary solutions for the Burgers equation
Journal of the American Mathematical Society


We construct space-time stationary solutions of the D Burgers equation with random forcing in the absence of periodicity or any other compactness assumptions. More precisely, for the forcing given by a homogeneous Poisson point field in space-time we prove that there is a unique global solution with any prescribed average velocity.

Ergodic Properties of Random Billiards Driven by Thermostats
Communications in Mathematical Physics


We consider a class of mechanical particle systems interacting with thermostats. Particles move freely between collisions with disk-shaped thermostats arranged periodically on the torus.
