Presentation
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.
This work is useful for improving the atmospheric dispersion models used in crisis management by IRSN's Crisis Technical Centre (CTC). 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.
