Microbial imprint on Earth materials


Welcome to the homepage of Dr Alice Bosco Santos, Junior Lecturer at the Institute of Earth Surface Dynamics, University of Lausanne, Switzerland.

My research focuses on unraveling how microbes shape the planet’s chemistry.

I investigate microbial signatures in lakes, the ocean, ancient sedimentary rocks, and experimental laboratory incubations where I can see the process in real time.

I bridge geology-biology by creating interdisciplinary datasets, ranging from molecular (16S rRNA, PCR, microbial cultivation, and manipulations), isotopic geochemistry (C, N, S, Sm/Nd, U/Pb, Fe) and mineralogy/petrology (microscopy, SEM, XRD), reflecting my holistic approach to solving scientific questions.
