I am interested in mathematics and physics of phase transitions. Different aspects of the theory of phase transitions; Pirogov-Sinai theory and cluster expansions, finite-size effects, zeros of partition function, annealed dilution, interfaces and wetting, equilibrium crystal shapes, dynamics of lattice models and crystal growth. Quantum lattice models.
