Welcome to my homepage!

I am a mathematician currently working as a visiting assistant professor at University of Copenhagen, where I was a Marie Curie fellow March 2018 through February 2020. My research interests lie in algebraic topology, in particular string topology of classifying spaces and its applications to group homology and cohomology.

I received my PhD from Stanford University in 2010. My advisor there was Professor Ralph Cohen.
