Daniel Ariztegui

Professor Daniel Ariztegui is a leading researcher in limnogeology and geomicrobiology at the University of Geneva. His work focuses on reconstructing paleoenvironments using lacustrine and marine sediments, with particular emphasis on biogeochemical cycles, microbial processes, and subsurface biosphere dynamics. He has supervised multiple PhD students and leads international drilling projects like the Dead Sea Deep Drilling Project (DSDDP) and the ICDP Towuti Drilling Project. His research integrates fieldwork, laboratory analyses, and genomic techniques to understand climate change impacts and environmental evolution.

• Teaching: Limnogeology, Global Change, Quaternary Paleoclimatology, Paleogeography
• Administrative Roles: President of the International Sedimentological Commission (ISC), Associated Editor for Sedimentology and Swiss Journal of Geosciences

Research highlights include studies on microbialite formation in Patagonia, arsenic enrichment in Dead Sea microbial mats, and strontium bioremediation using green algae. His fieldwork spans Argentina, Guatemala, Chile, and Indonesia, with ongoing projects in Lake Petén-Itza and Lake Chad.

Key contributions include over 50 peer-reviewed publications since 2020, focusing on paleohydrology, microbial biomineralization, and climate-ecosystem interactions. Current grants support investigations into Dead Sea lake levels, Pampean lake systems, and subsurface biosphere dynamics.
