I am a post-doc at the Mathematics Department of Florida State University. Here is my CV. My contact info (including office hours) can be found on my departmental page. Soon I will set up a personal page and put some more interesting stuff there.
In the past few years I have been occupied with stacks. More specifically, these days I am writing up some foundational material on topolgical stacks. Other than that, I am involved in a project on string topology for topological stacks (with Kai Behrend, Greg Ginot, and Ping Xu). I am also working out a generalization of Fulton-MacPherson's bivariant theories so that they can be applied in certain stacky settings. As a side, I am trying to understand differential geometry of gerbes "banded" by 2-groups.
Apart from this, I am also interested in arithmetic geometry and noncommutative geometry .
A list of my papers and preprints can be found here.
This semester I am teaching Calc I. Follow the link MAC2311 for the course material.
