Laurent Berger, mathematician, UMPA



Laurent Berger is a mathematician at ENS de Lyon, in the Unit of Pure and Applied Mathematics (UMPA).

Born in 1976, Laurent Berger studied mathematics in Paris, at École normale supérieure and at the University of Orsay from 1995 to 1999. He supported a thesis at Université Paris 6 – p-adic representations and differential equations – under the supervision of Pierre Colmez. During his thesis, he worked twice in the United States, at the University of Massachusetts in Amherst and at Brandeis University. In 2002, he was a post-doc at Harvard University.

He then obtained a researcher position at the CNRS, assigned to the University of Orsay and the IHES. At the same time, he taught "small groups" at the École Polytechnique. He finally joined ENS de Lyon in 2007 as a university professor. He worked as a junior member of Institut Universitaire de France from 2012 to 2017, and he is currently a Distinguished University Professor.

Laurent Berger works in the theory of numbers and arithmetic geometry. His favorite themes are the Galois p-adic representations, the (Phi, Gamma)-modules, and the Langlands p-adic program.
