Rate My Professor Christophe Dupraz

Christophe Dupraz serves as Associate Professor of Geomicrobiology in the Department of Geological Sciences at Stockholm University. He earned his PhD in 1999 from the University of Fribourg, Switzerland, with a dissertation titled "Paléontologie, paléoécologie et évolution des faciès récifaux de l’Oxfordien Moyen-Supérieur (Jura suisse et français)." Prior to his current role, he was affiliated with the Institut de Géologie at the University of Neuchâtel, contributing to studies on microbial processes in stromatolites. Dupraz also completed a diploma thesis on the geology of the Moutier region (Moron and Graitery).

His research centers on geomicrobiology and carbonate sedimentology, exploring microbe-mediated carbonate precipitation, early diagenesis, and microbialite formation in modern environments such as hypersaline lakes in the Bahamas and Shark Bay, Australia. Key publications include "Processes of carbonate precipitation in modern microbial mats" (Earth-Science Reviews, 2009), "The role of microbes in accretion, lamination and early lithification of modern marine stromatolites" (Nature, 2000), "Microbial lithification in marine stromatolites and hypersaline mats" (Trends in Microbiology, 2005), "Exopolymeric substances of sulfate-reducing bacteria: interactions with calcium at alkaline pH and implication for formation of carbonate minerals" (Geobiology, 2007), "Microbe–mineral interactions: early carbonate precipitation in a hypersaline lake (Eleuthera Island, Bahamas)" (Sedimentology, 2004), "Microbe-Mediated Mn Oxidation—A Proposed Model of Mineral Formation" (Minerals, 2021), and "Microbialite Accretion and Growth: Lessons from Shark Bay, Western Australia" (Annual Review of Marine Science, 2024). These works have garnered thousands of citations, highlighting his impact on understanding ancient microbial ecosystems.

At Stockholm University, Dupraz leads courses including Geomicrobiology and Minerals (GG7036), Origin and Early Evolution of Life (GG1102), Biogeochemistry (GG8115), and Earth I - Geology (GG2008). He serves as Student Counsellor for distance learning and is a member of the IGV's Geochemistry group, which studies planetary chemical and biogeochemical processes.
