About me

Currently, I am a postdoc in the Department of Mathematics of the University of Luxembourg, part of the research group of Sarah Scherotzke and Pieter Belmans.

Before that I was a PhD student at the University of Glasgow under the supervision of Michael Wemyss and Ben Davison. After finishing my PhD in 2021, I spent a year as a guest researcher at the Max-Planck institute in Bonn, before moving to Luxembourg.

My research centres on the interaction between enumerative geometry and representation theory. I am interested in enumerative invariants, moduli spaces of quivers, Hall algebras, deformation theory, derived categories, A-infinity algebras, among many other things.

My main research area is the part of enumerative algebraic geometry called refined Donaldson--Thomas theory, which is concerned with counting sheaves on complex threefolds. To compute these sheaf counts one has to understand various moduli spaces, which are often quite complicated beasts.

There are various tools one can use to study the moduli spaces appearing in DT theory. The ones I care about are:

The main goal of my research is to make new contributions in these areas, in order to advance our understanding of enumerative geometry. In particular, I am looking to develop techniques that work in noncompact settings, which would allow us to reason about moduli spaces and their invariants using local arguments. Typical examples of such noncompact spaces are crepant resolutions of singularities appearing in the threefold minimal model program, which I studied during my PhD and afterwards.

Currently I am working on a project involving differential-geometric deformation theory, in order to understand analytic open neighbourhoods of moduli spaces. I am also looking into noncommutative projective geometry, together with other members of the working group in Luxembourg.
