Luis Scoccola

I am a CRM-ISM fellow, affiliated with the Laboratoire d'Algèbre, de Combinatoire et d'Informatique Mathématique at the Université du Québec à Montréal and with the Université de Sherbrooke. Previously, I was a postdoctoral research associate in the department of mathematics at the University of Oxford.
