Research interests
In the context of my PhD project I work with Chow-Witt groups aka Milnor-Witt cohomology. My goal is to compute these for motivic classifying spaces of certain finite groups. Currently I am also part of a team project in chromatic homotopy theory, organized via Women in Topology IV, working on computing the (exotic) Picard group of the K(n)-local category for n=p-1. In addition I am interested in higher categories and algebraic and hermitian K-theory.
