Education

Ph.D. (2006) Yale University and Université Paris-Sud

Research Area: Geometric group theory, ergodic theory, rigidity

My research interests lie in the area of geometric group theory and Lie group theory, dynamics of group actions on manifolds and more generally on polyhedral complexes. I am especially interested in group actions on trees and buildings, lattices of the automorphism groups of trees and buildings, lattices of algebraic groups over local fields, their rigidity and their dynamics.
