Development of the Accelerator Mass Spectrometry (AMS) technique and application of cosmogenic nuclides to problems in the geosciences.

My research interests focus on improving the AMS technique performances for commonly used cosmogenic nuclides such as 10Be, 26Al, 36Cl and 129I, on developing detection procedures for new cosmogenic nuclides of interest, on improving our knowledge of the production mechanisms of the cosmogenic nuclides, and on applying cosmogenic nuclides to the quantification of the various processes (tectonics, climate, …) affecting and modelling the Earth’s surface over the last few millions years.

In conjunction with my position as Professor at Aix-Marseille University, I teach courses in geosciences and geochronology. In addition, I have mentored and still mentor PhD students on the analytical techniques and interpretive approaches associated with the application of cosmogenic nuclides to earth science problems.
