Professor at the University of Birmingham, UK.
I am interested in constructive mathematics and (constructive and non-constructive) homotopy type theory and univalent foundations, connections of topology with computation, (infinity) topos theory, locale theory, domain theory, combinatorial game theory and much more.

Fulltime freelance provider of outreach and enhancement in maths ... I talk a lot. About maths.

I talk about other stuff too, like ballroom dancing, juggling, unicycling, education, engineering, software, and "other things".

But mostly about maths.

I tend to follow back, but only if you have something in your profile.
