Research

Some open problems I don't know how to solve

My research themes

• Branching random walks: asymptotic behaviour of extremal processes, additive martingales, large deviations, inhomogeneities in space and time, selection.
• Branching Lévy processes.
• Coalescent processes: small time asymptotics, number of blocs, interaction with fragmentation processes, dual.
• Infinite bin models.
• Statistical physics models: Derrida--Retaux model, generalized random energy model, branching-selection particle systems.
• Humanoïde robots: bipedal displacement, stability of noisy control.
• Testing strategies: binary and non-binary pooling techniques, etc.
• And many more, possibly depending on my next random interaction.

I will try to add on this page some informations on these models, and maybe some projects I'm currently involved in.
