Research |
My research interests include algebraic topology
(especially stable homotopy theory and model categories),
homotopy type theory and univalent foundations,
category theory (especially higher categories),
derived categories,
modular representation theory,
mathematical physics (quantum gravity),
and computation.

What's this? |
Chris Kapulkin and I are running the Homotopy Type Theory Electronic Seminar Talks.
Graduate students: I am looking for new graduate students for 2021 in the areas of homotopy theory, homotopy type theory and topology, broadly construed. If you are interested, please contact me and send an application to our department mentioning my name. To be sure your application can be evaluated fully, please have at least three people submit detailed letters of reference, and also include information about the contents of the courses you have taken.
Postdocs: I encourage eligible people to apply for an NSERC Postdoctoral Fellowship, an NSERC Banting Postdoctoral Fellowship (domestic and international applicants eligible), any other NSERC postdoc, an NSF PDF, or similar to be held at Western. The standard NSF postdocs can be held in Canada, and there are other eligible NSF postdocs, e.g. an International Research Fellowship Program postdoc or a Mathematical Sciences Postdoctoral Research Fellowships.
Students and postdocs: The Canadian Government has many scholarships and fellowships that are available for people from many different countries.

SAGE is a wonderful program which interfaces to Magma, Maple, Mathematica and MATLAB, and the free programs Axiom, GAP, GP/PARI, Macaulay2, Maxima, Octave, and Singular. It is freely available and open source. If you find math fun, consider becoming a math major. Talk to me or anyone else in the department if you're curious. Here are some photos from trips I have been on. |
I've produced plots of roots of polynomials, some of which appeared in a Scientific American article. |
