Geochemistry of volcanic/hydrothermal systems.
The main objective here is to use gas and water geochemistry changes as a tool for volcano monitoring. It includes the chemical classification of the types of fluids according to their origin (e.g., volcanic, meteoric…) as well as the study of equilibrium condition for such fluids (as a function of temperature, pressure – hence depth – and geochemical buffers which govern rock-water interactions). Supervision of a PhD student (Erouscilla Joseph) on the subject.

Geological Mapping and Geochronology in Northern Dominica.
Current research focuses on the detailed geological mapping and geochronology (Ar/Ar) of the Morne Aux Diables (MAD) dome complex in northern Dominica. The MAD volcanic complex has been experiencing elevated seismic activity since June 2009 and an updated detailed geological map of the area is needed for improved hazard and risk assessment. This research also involves field mapping and various geochemical techniques on samples collected.
