Teaching
Teaching has always been and will remain an important part of my mathematics experience. My teaching statement and teaching reviews are available upon request, and my CV has more detail.

Algebraic Topology I
I am the instructor for Algebraic Topology I (V4D1) at the Universität Bonn this semester, co-taught with Markus Hausmann. The topics are the Serre spectral sequence and its applications, Serre classes, rational homotopy groups of spheres, Steenrod squares, vector bundles, characteristic classes, and bordism.
