I am a postdoctoral researcher at the University of Edinburgh since September 2021. Between September 2018 and September 2021, I was a PhD student at the Laboratoire de Mathématiques d'Orsay, in the team Arithmétique et Géométrie Algébrique, supervised by Olivier Schiffmann. During my PhD, I have been interested in the Hall algebra of quivers, curves and their geometric incarnations: Ringel's construction of the positive part of the quantum group, Lusztig perverse sheaves,...

Seminar

With Ben Davison and Sebastian Schlegel Mejia, we are organizing the EGRET seminar in Edinburgh.
