Exploring the interactions between Earth and Life

 

I am a geomicrobiologist and environmental geochemist fascinated by how life shapes our planet, and how geological processes shape life in return.

My research explores the interactions between the geosphere and biosphere, from microbial metabolisms and mineral interfaces to sedimentary systems and Earth's environmental evolution. I am particularly interested in how biological activity transforms minerals, redistributes elements, and leaves traces in the geological record, as well as how geological conditions influence the development and preservation of life.

From hypersaline lakes and geothermal systems to the deep subsurface, I investigate extreme and often poorly explored environments. Combining field geology, scientific drilling, geochemistry, mineralogy, microscopy, and molecular biology, I connect processes across spatial and temporal scales to better understand metal cycling, mineral weathering, biogeochemical transformations, and the formation of biosignatures.

Beyond reconstructing Earth's past, I am interested in how this knowledge can help address present and future environmental challenges, from resource management to carbon cycling and emerging environmental technologies.

My approach is driven by curiosity, interdisciplinary thinking, and a conviction that some of the most exciting discoveries happen where scientific boundaries meet.
I am also the 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 : 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.
