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 concerned the geometry and topology of locally symmetric spaces and arithmetic groups, as well as their
cohomology
In mathematics, specifically in homology theory and algebraic topology, cohomology is a general term for a sequence of abelian groups, usually one associated with a topological space, often defined from a cochain complex. Cohomology can be viewed ...
, and their connection to number theory, in particular to Hilbert's 12th problem.
Some of his publications showed an interest in
Oulipo, referencing
An Attempt at Exhausting a Place in Paris by
Georges Perec
Georges Perec (; 7 March 1936 – 3 March 1982) was a French novelist, filmmaker, documentalist, and essayist. He was a member of the Oulipo group. His father died as a soldier early in the Second World War and his mother was killed in the Ho ...

Jacques Roubaud.
