Tensor categories. Invariant theory. Cohomology of groups. Current Research In my current research I apply techniques from geometric invariant theory (GIT) to study Hopf algebras and related structures. GIT techniques, combined with Schur-Weyl duality, enabled me to give a complete set of scalar invariants for semisimple Hopf algebras and for 2-cocycles on a given finite dimensional Hopf algebra. Some of these invariants are well known, and arise also in representation theory or in topological quantum field theory (TQFT). Others have an unfamiliar nature. the GIT technique also enab
