Areas of interest:

• Probability models from physics (statistical mechanics)--percolation, Ising model, Potts model, first passage percolation, and other models on a lattice.  Polymers, Gibbs distributions, interfaces.
  
• Subadditive Euclidean functionals on random point sets--minimal spanning trees, traveling salesman problem.
• empirical processses and probability in Banach spaces.
