Thibault Damour is a French physicist.
He is a professor of theoretical physics at the Institut des Hautes Ã‰tudes Scientifiques since 1989. An expert in general relativity, he has long taught this theory at the Ã‰cole Normale SupÃ©rieure. He contributed greatly to the understanding of gravitational waves from compact binary systems, and with Alessandra Buonanno, he invented the "effective one-body" approach to solving the orbital trajectories of binary black holes. He is also a specialist in the string theory.
