Early life and education

Bertoin was born in Lyon and completed his undergraduate studies at the École Normale Supérieure of St Cloud.^[2] He received his doctorate from University of Paris VI in 1987, having been advised by Marc Yor.^[3]

Career

Bertoin is a specialist in probability theory. His research deals with Lévy processes, Brownian motion, branching processes, random fragmentation, and coalescence processes.^[2]

In 1988, Bertoin became a researcher at CNRS, and was appointed Professor at Pierre-and-Marie-Curie University in 1992.^[2] In the early 1990s he began a collaboration with Ron Doney on the topic of conditioned random walks, with the pair co-writing six papers between 1994 and 1997.^[4]

Bertoin has received numerous awards, including the CNRS Bronze Medal (1992), the Rollo Davidson Prize (1996), and the Thérèse Gautier Prize (2015). He was an invited speaker at the ICM (2002) and ECM (2012), and elected a corresponding member of the Mexican Academy of Sciences in 2011.^[2]

His doctoral students include Grégory Miermont.
