I am a mathematician, currently working as a postdoctoral researcher at the Max-Planck Institute for Mathematics. I recently finished my PhD at the University of Glasgow, supervised by Michael Wemyss and Ben Davison.

My research centers around problems from algebraic geometry, which I tackle using various techniques from representation theory, deformation theory, and category theory. At the moment I am looking at singularities arising in the minimal model program, and methods of extracting refined Donaldson-Thomas invariants from such spaces.

In my thesis I developed some new techniques to understand the Donaldson-Thomas theory for families of threefold flops, mostly based on tilting theory. The thesis is available here, and the main results are also contained in this pre-print.
