About Me

Hello, I’m Fiona Blackett.

I’m a mathematics PhD student at the University of Strathclyde, advised by Dalton Sakthivadivel and Jules Hedges. I’m broadly interested in applying homotopy theory to mathematical physics, mostly from the perspective of cohesive $(\infty,1)$-topoi and differential cohomology, as well as $A_\infty$ and other homotopical structures in Floer homology and mirror symmetry.

I am employed & funded by VERSES AI as a researcher in the mathematics theory group, where I am currently working on active inference, topological data analysis, and applying statistical physics to machine learning.

I was previously in information security, and I still maintain some interest in formal verification and formal methods in software. This is mostly in the form of category theory intersecting type theory, with the MSP group at the University of Strathclyde.

In my time outside mathematics I enjoy hiking, cycling, and American Sign Language.
