Talks

The following are a selection of recorded mathematical talks I have given:

Equivariant Full Exceptional Collections in Algebraic Geometry (2026)

A (slightly choppy) Zoom recording of my PhD candidacy talk, given at UT Austin. Candidacy is the penultimate milestone before defending the PhD. I discuss full exceptional collections generally, and report on work of Castravet and Tevelev. (Recording credit: Luisa Velsaco)

The Representations and Subgroups of SL_d(Z) (2021)

A 12 minute video describing the ideas in my Honours thesis. It should be comprehensible to any undergraduate student who knows what a representation is. (apologies for the audio)

The sum of reciprocals of primes diverges (2021)

We prove that the sum of reciprocals of primes diverges. We use nothing more than the power series for log. This 8 minute talk was done as part of my Honours year, where students were asked to record a short talk discussing a piece of mathematics they like.
