As a mathematician, my field is Algebraic Geometry with a special interest in the geometry of algebraic surfaces.
I am one of the coordinators of the dualdegree Bachelor in Mathematics and in Economy and one of the coordinators of the Master in Mathematics delivered by the Universities of Nantes and Angers.
