Centres d'intérêt et projets de recherche

The role of volatiles - water or carbon dioxide - in geologic processes

The use (and abuse) of noble gases in tracing fluid and heat sources in the Earth. He and Ar are especially suited to deconvolving mixtures of mantle and surface fluids and are excellent probes of the magmatic/hydrothermal interface

Previous investigations have included analyses of hydrothermal deposits from Portugal; from Yunnan Province, China; from Nevada and California, USA; analyses of basaltic glasses from Iceland; from the mid-Atlantic Ridge; from the South East Indian Ridge; and numerical simulations

Calibration of the rate of production of cosmogenic noble gases at the Earth's surface. Collaboration with Alice Williams (post-doctoral researcher under the CRONUS-EU Marie Curie Research Training Network)

Interplanetary dust accumulation (traced using 3He) as a sedimentological tool, focused on the Neoproterozoic

Technical improvements: noble gas emultiple collector mass spectrometry, extraction by excimer laser ablation

Sampling the erupting volcano Oldonyo Lengai in July 2005 (pictures and movie!)
