Research topics: Stochastic population dynamics (and their simulation), interacting point processes, averaging in random environment, human longevity and mortality by socioeconomic circumstances, demographic risks and pension design, dynamic utilities.

IBMPopSim R package

• Package documentation and examples (2020).

I am the co-author, with D. Giorgi and V. Lemaire (LPSM, Sorbonne-Université) of the R package IBMpopSim, available on the CRAN. The IBMPopSim package aims at simulating the random evolution of a wide range of heterogeneous populations models, called stochastic Individual Based Models (IBMs). Such models have various applications in fields including actuarial sciences, biology, demography, or ecology.
