Current interests
Branching processes and applications to high energy physics.
I am currently working mainly on branching random walks (with or without selection), an interdisciplinary subject at the interface between statistical physics and its applications, in particular to the theory of evolution in biology, and mathematics. My interest in the general study of these stochastic processes is actually rooted in problems of particle physics, the latter being my training specialty. My previous research has indeed shown that such processes are involved in the microscopic description of very high energy particle collisions, for which they constitute an effective theory of quantum chromodynamics. In particular, I have shown that the statistics of the extremes in the branching random walks correspond to the total cross sections of electron-atomic nucleus interactions, while some properties of the genealogies are found to be related to the diffractive cross sections.
