He is a professor at the Université Paris-Sud 11 and the École Normale Supérieure in Paris. His main research field is geometry. His contribution to mathematics was celebrated by a double event (a conference and a workshop)[1] co-organized for his 60th birthday by the Clay Mathematics Institute.
Pierre Pansu is the grandson of French physician, and the great grand-nephew of mathematician and astronomer Ernest Esclangon, inventor of the talking clock, and brother of Robert Pansu, chemist and research director at CNRS.
