I am interested in both low-dimensional topology and geometry - with a focus on knot theory, and combinatorial algebraic topology - with a focus on graph homologies. My research up to now has been mostly centered around knot homologies, quantum invariants, and their applications. I am currently working (also in collaboration) on various projects concerning Khovanov-Rozansky sl(N)-homologies and their deformations, the study of knot and link concordance from different perspectives, quantum invariants for knots and links, and Legendrian and transverse knots. Recently, I started working also around graph homologies, simplicial complexes associated to graphs, and their applications.
