RESEARCH INTERESTS AND BACKGROUND
My research interests are focused on the study of environmental interfaces between water, minerals and microorganisms. I search to understand and quantify the feedbacks between those three compartments and their effects on the development of ecological niches. I use field, laboratory and modeling approaches to study this problematic at a broad range of scales going from catchments to micromodels.
During my PhD at University of Rennes, I particularly worked on understanding how groundwater flow, by the transport of dissolved oxygen, plays a critical role on determining the redox conditons in the continental subsurface. This has important consequences on the availability of dissolved elements that are energetic sources for microorganisms, thus determining favorable ecological niches.
