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,...


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



My defense took place on July, 13th 2021. A version of my PhD thesis written under the direction of Olivier Schiffmann is available here and the handwritten notes for the presentation are there.
