Researcher in neutronics and reactor physics with applications in the field of nuclear criticality safety.My interests in the field includes :- Theoretical developments in the description of the nuclear chain reactions in terms of stochastic processes. I am currently working on the development of field theoretic approaches to model the transition to criticality in a nuclear system.- Monte Carlo simulations and Monte Carlo code developements : I am responsible for the development and maintenance of the VESTA depletion code (C++) and its associated AURORA companion tool (Java/Swing). I am also a member of the development team of the neutron transport Monte Carlo code MORET.- Multi-physcis modeling (mainly using OpenFOAM) with application to the modeling of criticality accidents.Competences :- Python, Java, C++ and Fortran programming languages- Neutron and reactor physics
