Welcome!
Welcome!
I hold a PhD in physical volcanology from the Université Paris Cité (France). Currently, I am a postdoc fellow (ClerVolc fellowship) at the Université Clermont Auvergne. I use 1-D models of volcanic columns and 2-D models of tephra dispersal, satellite data, laboratory experiments and field data to better understand the dynamics of explosive volcanic eruptions, and to assess volcanic hazards related to these events. Geologist by training, I collected and interpreted my own field data in order to reconstruct the eruptive history of the Mount Pelée (Martinique, Lesser Antilles). Passionate by volcanology since my childhood, my main goal is to link academic research and societal challenges through volcanic hazard assessment, with a focus on volcanic islands.
Skim through my research and publications pages to learn more about what I do. I also consider the communication between researchers and the population a matter of great importance, so please have a look at my outreach page. Finally, I am passionate about travel and photography: let your mind wander here!

SCIENTIFIC ACTIVITY
Explosive volcanic eruption dynamics
Field-based reconstruction of eruptive activity
Volcanic hazard assessment & monitoring of on-going eruptions
Impact of wind on the mixing in turbulent jets
CURRENT RESEARCH: Modeling of processes and hazards associated to small explosive volcanic eruptions (VEI ≤ 3)
ClerVolc Postdoctoral Fellowship, granted in 2024
Université Clermont Auvergne, Laboratoire Magmas et Volcans
The purpose of this project is to improve our knowledge of the dynamics and impacts of small explosive eruptions (VEI 3 or smaller). This better understanding will allow the characterization of the hazards associated to these eruptions, with a focus on ash fallout and ballistics.
The project includes theoretical modeling, dispersal simulations (including hazard assessment), and fieldwork. This integrated strategy will be applied to two volcanic regions: the maar of Jaude (Puy-de-Dôme, France) and Mayotte (Comoros archipelago).

Phd award ccr cat nat 2020
Phd award ccr cat nat 2020
I received in June 2020 the PhD award CCR Cat Nat for my thesis entitled: "Dynamics of Plinian eruptions: re-assessment of volcanic hazard in Martinique".
The purpose of the CCR Cat Nat PhD award is to reward a doctoral thesis in the area of natural disasters with a potential application to the insurance industry and the prevention of risks. The thesis has to demonstrate innovative, detailed and original research and provide insight on the theoretical aspects and practical issues associated with the thesis topic.
The Prix CCR Cat Nat is open in the European area and the winner is chosen by a jury composed of university academics, research and insurance sector experts and CCR representatives.
