Research interests

• Volcanic provinces as a marquer of geodynamic processes
• Natural hazards in volcanic environments including eruptive dynamics and mass-wasting processes (large flank collapses, debris-avalanches and tsunamis, caldeira formation and pyroclastic eruptions, shallow landslides, rockfall, lahars, debris flows...)
• Hydrology of volcanic systems : tracing rainfall infiltration and groundwater circulation along major geological discontinuities

Research skills - approaches

• Geological mapping in volcanic areas
• K/Ar and Ar/Ar geochronology on separated phases
• Magma geochemistry (major and trace elements, Sr, Nd, Pb and Hf isotopes)
• Morpho-structural analyses of volcanic edifices, dyke swarms, gravitational failures and associated deposits
• Quantification of the volumes erupted and destructed by mass-wasting processes on various time-scales
• Water geochemistry (major cations and anions, d¹⁸O, d²H, d¹³C, ¹⁴C): quantifying the effects of climate and geology on rainfall infiltration, groundwater flow, superficial runoff, alteration and erosion in volcanic areas

Selected targets and case studies
