Research Interests

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.
