My field of study is geometric topology. I am interested in various minimality questions. Among them is the study of the genus function of manifolds in dimension 3 and 4.

One of my favourite tools for studying these questions is twisted Reidemeister torsion. It is connected to Seiberg-Witten theory and the classical Alexander polynomial for knots.
