I am fascinated by one fundamental question: how does biology become geology? My research explores how microorganisms shape the signatures of life that we observe in sediments, rocks, and potentially on other planets. By combining microbiology, geochemistry, ecology, biophysics, and astrobiology, I investigate the ecological, environmental, and geological controls that govern the formation and preservation of biosignatures.

My work focuses on understanding how microbial interactions, microscale environmental heterogeneity, and preservation processes influence the biological signals that persist through time. Through laboratory experiments, field studies, and quantitative approaches, I seek to connect processes occurring at the scale of microbial cells with the signatures used to reconstruct the history of life on Earth and to search for life elsewhere in the Universe.

At the Microbial Biosignatures Lab (MISI) at the University of Lausanne, I aim to build an interdisciplinary research environment where microbiology, geochemistry, ecology, and planetary science converge to address some of the most fundamental questions about the origin, evolution, and detectability of life.
