Liane G Benning

Liane G Benning is a Professor at Freie Universität Berlin and leads the Interface-Geochemistry group at GFZ Helmholtz Centre for Geosciences in Potsdam, Germany. Her research quantitatively examines biogeochemical reactions across inorganic and biological systems, with three primary focuses: (1) biogeochemical mineral-microbe interface processes, (2) nanoparticle formation and transformation in aqueous systems, and (3) microbial ecology in extreme environments such as polar ice sheets.

Her research integrates geomicrobiology, nanogeochemistry, and cryosphere science, specifically investigating:

• Glacier ice algae adaptations to polar conditions
• Iron-phosphate interactions in nanophases
• Mineral transformations (e.g., vivianite, green rust)
• Heavy metal speciation in laterites
• Microbial darkening of ice sheets
• Organic carbon export from iron-rich ecosystems

Analysis of her 15 most recent publications (2024-2025) reveals strong emphasis on:

• Greenland Ice Sheet microbial communities and their photophysiology
• Nanoscale iron-phosphate interactions and environmental implications
• Chromium mobility in iron-rich systems
• Glacial albedo feedback mechanisms
• Metagenomic exploration of extremophile biosynthetic potential
• Mineral phase transitions under varying redox conditions

She leads field and laboratory investigations at GFZ Potsdam, coordinating research on biogeochemical interfaces in polar, aquatic, and contaminated environments.
