I am a geomicrobiologist interested in how microbial communities, minerals, and chemical gradients interact to structure ecosystems. My work focuses primarily on lacustrine systems and their sediments, which represent chemically and biologically diverse environments where physical, chemical, and biological processes intersect across a wide range of spatial and temporal scales.

Lakes are also natural laboratories in which organic molecules, minerals, and microbial metabolisms become coupled under variable redox, salinity, and energy regimes. Understanding these interactions is essential both for interpreting sedimentary records and the past environments they record, and for identifying the conditions under which chemical processes are organized and maintained in natural systems.
My research integrates methods from geology, chemistry, and molecular biology to investigate these interactions. I combine sedimentological and mineralogical approaches (microfacies analysis, scanning electron microscopy, geochemical characterization of minerals and organic matter) with biological and molecular tools (epifluorescence microscopy, DNA and RNA analyses, gene quantification and sequencing) to study how microbial processes shape sedimentary chemistry. A particular focus of my work is on the imprint of microbial activity on the geological record, including the formation and fossilization of microbial mats, the development of microbialite structures, and the precipitation of organomineral phases such as carbonates and iron sulfides.

Through this interdisciplinary approach, my research aims to elucidate how mineral–organic interfaces, chemical gradients, and microbial metabolisms organize matter in sediments, providing insight into the processes that govern early diagenesis as well as broader questions related to the emergence and persistence of life.

I am also th co-founder of the scientific journal, called Sedimentologika. A journal that allows free access, free reading, free submission for all, under the model of "Diamond Open Access". Sedimentologika is a community-based initiative, and is open since 2023 and has published already 3 issues : visit the website and get involved in this open science initiative on www.sedimentologika.org  and check out the Sedimentologika social networks for more news !
