Some course materials from past teaching:

  • In Summer 2018, I taught Math 6080 at the University of Utah. The course webpage is here
  • In Spring 2018, I taught Math 5320 at the University of Utah. The course webpage is here



  • Definitions of the multiplicative group and group objects in categories pdf.
  • Coherence theorems in two-dimensional category theory pdf. This summary article was my Part III essay.


Several years ago, I met Alexander Grothendieck. I wrote an essay about it linked here. An abridged version of this essay appeared in Vol. 63, No. 3 of Notices.
