Presentation

Depuis ma thèse en physique de l'atmosphère obtenue en 2012, mes recherches portent sur le dépôt des gaz et des aérosols. En particulier, je travaille sur le lessivage des particules radioactives, c'est à dire comment les précipitations rabattent au sol les particules radioactives de l'atmosphère - que cette radioactivité soit naturelle ou d'origine humaine. Je travaille principalement depuis 2013 sur la modélisation du dépôt des radionucléides dans les [modèles de dispersion atmosphérique](https://en.wikipedia.org/wiki/Atmospheric_dispersion_modeling). Ces travaux sont utiles à l'amélioration des modèles de dispersion atmosphérique utilisés en gestion de drise par le [Centre Technique de Crise (CTC)](https://www.irsn.fr/savoir-comprendre/crise/organisation-moyens-adaptes-gestion-crise) de l'IRSN. À ce titre, je suis également équipier de crise pour le CTC. La réprésentation dépôt des radionucléides dans les modèles de dispersion atmosphérique est validé par des cas d'études. C'est ainsi que j'ai pu travailler sur la modélisation des conséquences de l'accident de Fukushima, et sur la modélisation du radon atmosphérique à l'échelle continentale. ## Expérience * 2019-... **[IRSN](https://www.irsn.fr/)**, Chercheur en physique de l'atmosphère, équipier de crise * 2017-2019 **Strathom Energie**, Chercheur consultant pour l'IRSN * 2015-2017 **[IRSN](https://www.irsn.fr/)**, Ingénieur-Chercheur en CDD * 2013-2015 **[CEREA](https://www.cerea-lab.fr/)** (Ecole Nationale de Ponts et Chaussées/EDF), post-doctorat * 2009-2012 **[IRSN](https://www.irsn.fr/)/[LaMP](https://lamp.uca.fr/)**, Thèse en physique de l'atmosphère ## Études * 2012 **Doctorat d’Université** Spécialité Physique de l’atmosphère, Université Blaise Pascal, ClermontFerrand, mention « très honorable ». * 2009 **Master** DIODE (Développement des Instruments scientifiques Optique et DEtection) de l’Université de Rouen : Optique, Métrologie, Mécanique des fluides, Traitement des images * 2007 **Licence** de Physique, Université de Caen Basse-Normandie
Since completing my PhD in atmospheric physics in 2012, my research has focused on the deposition of gases and aerosols. In particular, I work on the scavenging of radioactive particles, i.e. how precipitation washout radioactive particles from the atmosphere - whether this radioactivity is natural or man-made. Since 2013, I have been working mainly on modelling radionuclide deposition in [atmospheric dispersion models](https://fr.wikipedia.org/wiki/Mod%C3%A9lisation_de_la_dispersion_atmosph%C3%A9rique). This work is useful for improving the atmospheric dispersion models used in crisis management by IRSN's [Crisis Technical Centre (CTC)](https://www.irsn.fr/savoir-comprendre/crise/organisation-moyens-adaptes-gestion-crise). As such, I am also a crisis team member for the CTC. The deposition representation of radionuclides in atmospheric dispersion models is validated by case studies. This is how I came to work on modelling the consequences of the Fukushima accident, and on modelling atmospheric radon on a continental scale. ## Experience * 2019-... **IRSN](https://www.irsn.fr/)**, Researcher in atmospheric physics, crisis team member * 2017-2019 **Strathom Energie**, Research consultant for IRSN * 2015-2017 **[IRSN](https://www.irsn.fr/)**, Research engineer on fixed-term contract * 2013-2015 **[CEREA](https://www.cerea-lab.fr/)** (Ecole Nationale de Ponts et Chaussées/EDF), post-doctoral fellow * 2009-2012 **[IRSN](https://www.irsn.fr/)/[LaMP](https://lamp.uca.fr/)**, Thesis in atmospheric physics ## Academic career * 2012 **Doctorate in Atmospheric Physics, Blaise Pascal University, Clermont-Ferrand, with distinction. * 2009 **Master** DIODE (Développement des Instruments scientifiques Optique et DEtection) at the Université of Rouen: Optics, Metrology, Fluid Mechanics, Image Processing * 2007 **Licence** in Physics, University of Caen Basse-Normandie
