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.
