Research Overview

The Interface Geochemistry research group at GFZ is a very international, dynamic and interdisciplinary team, addressing research topics spanning biogeochemistry, materials science, chemical physics and inorganic (geo-)chemistry. Our focus is on the quantitative elucidation of “interfacial reactions” driving and controlling biogeochemical processes shaping our planet's surface and (near-)subsurface environments from the nano- to the global-scale. We combine experimental and field-based approaches with state-of-the-art analytical electron and X-ray characterization techniques and gain fundamental knowledge about interfacial reactions and their impact on the cycling of carbon, nutrients and trace elements in abiotic and biotic systems.
