My main interest lies in the formal and mathematical aspects of quantum field theory. In the past I have studied chiral lagrangians, string perturbation theory, and conformal field theory. In the past decade or so all my works have been related to the renormalization group in one way or another: more concretely I have worked on a new formulation of field theory in the coordinate space, introduction of geometry (connection) in theory space, high temperature phase transitions, and the Wilsonian exact renormalization group.
