I am a postdoc at the Hausdorff Center for Mathematics at the University of Bonn.

My research interests are in algebraic topology. In my current research project I am applying methods from equivariant homotopy theory to study Hermitian K-theory and L-theory, via an equivariant enhancement of the trace methods of Bökstedt, Hsiang and Madsen.
