My current research interest span the borders of Mathematics (combinatorics, asymptotic analysis of series, ODEs), Statistical Physics (critical phenomena, complex systems), and Computer Science (design of algorithms and parallel computing).
I am interested in how to count things efficiently by computer and how to obtain exact solutions and exact asymptotic information. I have worked on a number of classic problems from statistical physics and combinatorics, such as the Ising and Potts models, percolation, self-avoiding walks and polygons, lattice animals etc.
