My research interests are in 3-dimensional topology and geometry, knot theory, hyperbolic geometry, quantum topology and combinatorics. In the recent years I have been interested in exploring the interplay and relations between physics originated and combinatorial 3-manifold invariants, and geometric structures on 3-manifolds coming from the Thurston geometrization picture. For instance, I have been studying relations between quantum knot invariants, such as the Jones polynomial, and geometric structures of knot complements such as hyperbolic geometry and incompressible surfaces. More generally I have been studying relations between certain 3-dimensional TQFT structures and geometric structures 3-manifolds.
