I am a first (third) year grad student in Algebraic Topology at Columbia University. My advisor is Søren Galatius. Before that, I was a second year Phd Student at the University of Copenhagen, in the GeoTop center. Broadly speaking, I am interested in Geometric Topology and its interactions with Homotopy Theory.

You can now reach me at ap4753(at)columbia(dot)edu.
