Here’s the team of teachers in charge of this year’s courses, with whom you’ll have the opportunity to interact
Precambrian geology, sedimentology, geochemistry, geomicrobiology, Earth System Evolution, early traces of Life
Stefan is a CNRS researcher specializing in Precambrian sedimentology, geochemistry, and early microbial life at the European Institute for Marine Studies, a major French oceanographic institute situated on the outskirts of Brest, France. After undergraduate studies and graduate work in biology, geomicrobiology, and sedimentary geochemistry at McGill University and the University of Alberta, Stefan joined the Geo-Ocean laboratory in 2010, first as a postdoc in metal and metalloid stable isotope geochemistry, and then as CNRS researcher in 2013. His research program is focused on reconstructing environmental conditions and biospheric evolution on the primitive Earth, with particular focus on fossil records of early microbial life, the oxygenation of Earth’s atmosphere and oceans, and the evolution of Earth’s biogeochemical cycles. He has been heavily involved in international drilling projects targeting Archean and Proterozoic sediments of geobiological interest worldwide and led an ERC Starting Grant project from 2017 to 2023 examining the Archean origins of oxygenic photosynthesis and Earth’s carbonate factory. He has served on various national and international committees, including the French INTERRVIE and National Planetology Programs and the International Continental Scientific Drilling Program (ICDP). In 2019 he was awarded the EAG’s Houterman’s medal for early career contributions to geochemistry.
