My research on volcanic aquifers has focused on several French overseas territories, including Martinique, Guadeloupe (Bouillante geothermal field) and Réunion Island (Salazie).
These studies have addressed complementary aspects of groundwater systems in volcanic environments: groundwater recharge and resource assessment, the hydrogeological functioning of deep geothermal reservoirs, and groundwater flow and drainage in fractured volcanic formations.
Combining hydrogeological investigations, hydrochemical approaches, time-series analysis and analytical modelling, this work has contributed to a better understanding of the highly heterogeneous structure and hydraulic behaviour of volcanic aquifers, from shallow groundwater resources to deep geothermal systems.
