Fractured and karst aquifers


How can we represent the multiscale heterogeneity of aquifers in models that are physical enough to be predictive, yet simple enough to be operational?


I am a senior hydrogeologist working on the observation and modelling of groundwater systems, with a particular focus on fractured and karst aquifers. My research combines field observations, hydrological monitoring, tracer techniques, data analysis and modelling to investigate groundwater flow, recharge, storage and interactions with surface environments. A particular focus of my recent work is the functioning of coastal karst aquifers and submarine springs, including the Vise submarine spring in the Thau Lagoon, southern France.

Vise & Thau

A natural laboratory for coastal karst hydrogeology

The Vise is a submarine karst spring located in the Thau Lagoon, southern France

Its highly dynamic behaviour provides an exceptional opportunity to investigate groundwater flow in coastal karst systems, including flow reversal, saltwater intrusion and groundwater–seawater interactions.

My research on the Vise combines long-term monitoring, field observations and modelling.

Science communication 🇫🇷

I am committed to sharing groundwater science beyond academia through journalism, media, public talks and outreach activities.

I contribute to The Conversation France, where I explain groundwater, karst hydrogeology and water-related environmental issues to a wider audience.
