Dr. Toulier studies groundwater circulation in volcanic and tropical environments. He collects field data through hydro-climatic monitoring and utilizes the multidisciplinary approach in his study of how the aquifers are functioning. His research interest is in groundwater recharge, water balance estimation, hydrological conceptual models, and more specifically the quantification and impact of groundwater fluxes in Ridge-to-Reef management.
