Francis Bonahon

Francis Bonahon (9 September 1955, Tarbes) is a French mathematician, specializing in low-dimensional topology.

He received in 1975 his maîtrise in mathematics from the University of Paris VII, and in 1979 his doctorate from the University of Paris XI under Laurence Siebenmann with thesis Involutions et fibrés de Seifert dans les variétés de dimension 3.

In 1985 he received his habilitation from the University of Paris XI under Siebenmann with thesis Geometric structures on 3-manifolds and applications.

[2] Bonahon's research deals with three-dimensional topology, knot theory, surface diffeomorphisms, hyperbolic geometry, and Kleinian groups.

He received in 1985 a bronze medal from CNRS and from 1989 to 1994 a Presidential Young Investigator Award.
