Studying Rocks from the Depths of Space to Earth’s Wettest and Driest Zones!
——————————————————
Hello and welcome to my website!
I am a geologist with expertise in the geochemistry of rare earth elements (REE) and the study of meteorites. I employ a combination of mineralogical and geochemical measurements, including both elemental and isotopic analyses to investigate rock and soil samples.
As a permanent research scientist (chargé de recherche), I work for the French National Research Institute for Sustainable Development (IRD), and I am based in Géosciences Environnement Toulouse (GET).
If you are conducting any studies that involve geochemical analyses, I would be delighted to engage in discussions. I am open to exploring new collaborations and research opportunities.
Feel free to visit my website, and if you have any questions or inquiries, please don’t hesitate to contact me.
Exploring the Extremes!
From the hot deserts of Lut, Sahara, and Atacama…
…To the cold deserts of the Antarctic plateau…
…And forests of tropical Africa!
Research Interests
Rare Earths and Weathering
Meteoritics and Cosmochemistry
Petrogenesis of Magmatic Rocks
I have broad interests in the geochemistry and petrology of both terrestrial and extraterrestrial environments.
My current research focuses on two main areas. First, I investigate chemical weathering processes, with a particular emphasis on the behavior of rare earth elements (REEs) during weathering. Second, I study the geochemical mechanisms responsible for the formation of REE ores in both low- and high-temperature environments. In addition, I specialise in early solar system studies through the analysis of meteorites, and I examine the terrestrial weathering of meteorites recovered from Antarctica and hot desert regions.
