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.

Interface Geochemistry Seminar Series (IGSS)

List of the 3 talks of the seminar from January to March 2026
Seminar program winter 2026 (poster: section 3.5, GFZ)

The Interface Geochemistry Seminar Series (IGSS) tackles “interfacial reactions” in (bio)geochemical processes, ranging from surface to (near-)subsurface environments and from nano- to global-scales.
