The 1996 Rollo Davidson Prize recipient, Jean Bertoin, emerged as a prominent figure in probability theory through his investigations into Brownian motion and Lévy processes. Born in Lyon in 1961, he developed a significant body of academic work centered on random fragmentation, branching processes, and coalescence processes, contributing extensively to the foundational understanding of stochastic flows throughout his long career.
Academic Formation and Early Career
Bertoin completed his undergraduate studies at the École Normale Supérieure of St Cloud before moving to the University of Paris VI. Under the supervision of Marc Yor, he earned his doctorate in 1987. His early professional journey began in 1988 as a researcher at CNRS. By 1992, he transitioned to an appointment as a professor at Pierre-and-Marie-Curie University.

Take the IQ test →Contributions to Probability Theory
His research focuses on the mechanics of probability, specifically dealing with conditioned random walks and stochastic dynamics. During the early 1990s, he maintained a productive partnership with Ron Doney, resulting in the co-authorship of six papers between 1994 and 1997. Bertoin has also mentored students in the field, including Grégory Miermont.
Publications and Institutional Recognition
Bertoin has published foundational texts, including Lévy processes in 1996 and Random fragmentation and coagulation processes in 2006. His scholarly output extends to numerous articles, such as work on exponential functionals of Lévy processes with Marc Yor and studies on stochastic flows with Jean-François Le Gall. Since 2011, he has held a professorship at the University of Zurich and serves as a member of the Institut Universitaire de France. He was elected a corresponding member of the Mexican Academy of Sciences the same year.
