I am a geometric-topologist and my primary area of research is knot theory, braid groups and 3-manifolds. My research focuses on the construction of Jones-type invariants for knots and links in 3-manifolds other than the 3-sphere (skein modules), using knot algebras and Markov traces. Recently, I developed an interest on tied links, on pseudo knots & on knotoids and I introduced the concepts of tied pseudo knots and pseudo knotoids, which seem promising in serving as models for biological objects related to DNA & Proteins.
