Research
Overview
I am interested in low-dimensional topology and geometry, with a focus on knot theory. My research up to now has been 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, combinatorial invariants of links, and virtual knots. Here is a small list of some topics I am interested in.
Properties of Khovanov-Rozansky homologies and their deformations;
Combinatorial and homological invariants of graphs;
Finite-type invariants;
Combinatorial invariants of links;
Concordance of knots and links, obstructions to sliceness, slice genus computations and slice-torus invariants;
Computability and categorification of quantum invariants for links and 3-manifolds;
Invariants for surfaces in four dimensional spaces;
Invariants for graphs in three dimensional spaces;
Invariants for transverse knots and links arising from link homologies, their properties, and their applications to the study of braids;
Link homologies for virtual knots, and applications to the study of virtual concordance;
Properties of links with special symmetries;
Spacification of link homologies and their properties.
