Esther Schwarzenbach

Esther Schwarzenbach is a Professor in the Department of Geosciences at the University of Fribourg. She specializes in geochemical and tectonic processes, particularly focusing on sulfur cycling, serpentinite evolution, and subduction zone dynamics. Her work integrates field-based studies, isotope geochemistry, and experimental petrology to address fundamental questions in Earth science.

Her research interests include the geochemical evolution of the Earth's mantle, the role of fluid-rock interactions in subduction zones, and the cycling of volatile elements (e.g., sulfur, carbon) through geological time. She has led expeditions such as IODP 399 and 357, contributing to studies of oceanic lithosphere alteration and serpentinization processes.

Recent publications highlight investigations into Eoarchean sulfur recycling, sulfur transfer during serpentinite subduction, and the impact of fluid-rock interactions on isotope signatures. Her contributions span marine geosciences, metamorphic petrology, and early Earth history.

Labs/Teams: As a Group Leader in the Department of Geosciences, she oversees research on geochemical cycles and tectonic processes, though specific lab names are not explicitly stated in available materials.
