Haefeli Anja

Anja Haefeli is a Doctoral Student/Researcher at the University of Basel, affiliated with the Department of Environmental Sciences under the Faculty of Humanities and Natural Sciences. Her work focuses on biogeochemical processes in aquatic systems, particularly methane cycling and nitrogen fixation dynamics.

Her research aligns with the Aquatic and Isotope Biogeochemistry group led by Prof. Moritz F. Lehmann, contributing to studies on:

• Microbial methane oxidation in coastal environments
• Metal mobilization mechanisms in marine sediments
• Isotope proxy applications for nutrient cycling in lakes
• Priming effects in sediment organic matter decomposition

Recent publications highlight her expertise in interdisciplinary methods combining geochemistry, microbiology, and environmental monitoring. Her work addresses critical questions in climate change mitigation and ecosystem resilience. Contact: anja.haefeli@unibas.ch
