# Nicolas Bergeron

Nicolas Bergeron is a French mathematician born on 19 December 1975, who works in Pierre and Marie Curie University in Paris.

## Early career

Bergeron obtained his PhD at École normale supérieure de Lyon in the year 2000 under the supervision of Jean-Pierre Otal. His thesis was titled Cycles géodésiques dans les variétés hyperboliques ("geodesic cycles in hyperbolic varieties").

## Work

Bergeron's main interests are concerned with the geometry and topology of locally symmetric spaces and arithmetic groups, as well as their cohomology.

Some of his publications show an interest in Oulipo, referencing An Attempt at Exhausting a Place in Paris by Georges Perec. He has also written a (non-mathematical) article about Jacques Roubaud.

He is currently membre of the éditorial board of the journal Publications Mathématiques de l'IHÉS.
