A picture of me

I am currently a visiting scholar at Universität Hamburg. My research interests lie in algebraic topology and homotopy theory, 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.
