Prof. Thierry Adatte is a Swiss geologist and internationally recognized scholar in stratigraphy, sedimentology, mineralogy, and geochemistry. He earned his MSc and PhD in Geology from the University of Neuchâtel, Switzerland, and has developed a distinguished academic career devoted to understanding long-term Earth system processes and environmental change recorded in sedimentary archives.
He is currently Emeritus Professor at the Institute of Earth Sciences, University of Lausanne, where he previously served as Professor Titulaire and Head of the Sedimentary Geochemistry Laboratory. His research has made major contributions to the history of the Earth and the study of mass extinction events, integrating stratigraphic, mineralogical, and geochemical evidence to investigate deep-time environmental crises. His work focuses on the causes, timing, and consequences of major biotic turnovers, including the Cretaceous–Paleogene boundary, Permian–Triassic transition, oceanic anoxic events, and rapid climate perturbations such as the Paleocene–Eocene Thermal Maximum, offering key insights into Earth-system behavior under extreme conditions.
Prof. Adatte has extensive international research experience, including postdoctoral appointments in Mexico at the Instituto Mexicano del Petróleo and the Universidad Autónoma de Nuevo León, where he conducted research on sedimentary, mineralogical, and geochemical processes. These research stays contributed to long-term scientific collaborations and strengthened his expertise in applying Earth-system approaches to complex sedimentary records across diverse geological and tectonic settings.
In parallel with his research, Prof. Adatte has been actively engaged in university teaching since 1996, delivering courses in stratigraphy, sedimentology, paleontology, Earth system geochemistry, and field-based geological training. He has supervised and co-supervised numerous graduate theses, served on doctoral examination committees at universities in Europe and the Americas, and played an active role in the international geoscientific community through scientific societies, the organization of major conferences and field excursions, and contributions to scientific outreach through documentaries, media interviews, and advisory roles for museum exhibitions.
With more than 450 peer-reviewed publications and close to 18,000 citations, Prof. Thierry Adatte is widely regarded as a leading authority on sedimentary records of global change, mass extinction events, and the long-term evolution of the Earth system.
