Current Research

I am working in the area of geometry and topology in mathematics. My interests cover 3-dimensional manifolds, braid groups, knot theory, and the geometry of configuration spaces and moduli spaces. In attempting to construct representations of braid groups based on iterated integral of logarithmic forms, I found a relation between the monodromy of the KZ equation in conformal field theory and quantum groups. My recent research achievements include integral representation of the space of conformal blocks by multi-variable hypergeometric functions, geometry of infinite dimensional spaces such as the space of knots and the loop spaces of configuration spaces and the algebraic structure of their homology.
