Welcome to my personal page !

I am currently a post-doc in the team PEIPS at theCMAP at Ecole Polytechnique.

In case you would like to learn more about my curriculum, you can find here my CV .

You can find here more information on the longevity seminar at University Paris 6.

Research topics: Stochastic population dynamics (and their simulation), interacting point processes, averaging of stochastic processes, stable convergence, longevity risk, mortality by socioeconomic circumstances.






Research

My investigations with the study of stochastic ”microscopic” heterogeneous population dynamics. I apply pathwise representations of point processes as solutions of stochastic differential equations driven by Poisson measures in order to reduce the complexity of these dynamics and better under the aggregated dynamics they produce, with applications to the study of human longevity.
