Dan Christensen

I am a Professor in the Department of Mathematics at The University of Western Ontario in London, Ontario, with a cross appointment to the Department of Applied Mathematics, and an affiliation with the Perimeter Institute for Theoretical Physics. The Departments of Mathematics and Applied Mathematics are part of the School of Mathematical and Statistical Sciences.

I am the Graduate Chair for the Department of Mathematics, and am a Managing Editor of Homology, Homotopy and Applications.

My papers, preprints and talks.

Research

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

My papers, preprints and talks.

Chris Kapulkin and I are running the Homotopy Type Theory Electronic Seminar Talks.

I encourage eligible people apply for an NSERC Postdoctoral Fellowship, an NSERC Banting Postdoctoral Fellowship (domestic and international applicants eligible), any other NSERC postdoc, an NSF PDF (e.g. a International Research Fellowship Program postdoc, or a Mathematical Sciences Postdoctoral Research Fellowships or a Distinguished International Postdoctoral Research Fellowship), or similar to be held at Western.

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.

polynomial roots
I've produced some beautiful plots of roots of polynomials, some of which appeared in a Scientific American article.
