I wish the SFU climbing gym were not closed. There is a petition to reopen it here

I work on the unceded traditional territories of the Coast Salish peoples, including the səl̓ilw̓ətaʔɬ (Tsleil-Waututh), kʷikʷəƛ̓əm (Kwikwetlem), Sḵwx̱wú7mesh Úxwumixw (Squamish) and xʷməθkʷəy̓əm (Musqueam) Nations.


    In Fall 2024 I will teach the following courses:
  • Math 157 (all course information will be on canvas)
  • Math 818. The course webpage is here.

Upcoming Talks:

  • A note on travel availability: I cannot travel to any states or countries where I could be denied life-saving medical care or face criminal charges for a normal medical event.

Some course materials from past teaching:

  • In Fall 2023, I taught Math 817 at SFU. The course webpage is here
  • In Fall 2023, I taught a reading course on abelian varieties at SFU. The course webpage is here
  • In Summer 2018, I taught Math 6080 at the University of Utah. The course webpage is here

  • 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.
