Welcome to my homepage!

I am a mathematician currently working as a visiting assistant professor and Marie Curie fellow at University of Copenhagen. 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.
