3-year PhD position (m/f/d): Sulfur Cycling in Wetlands and its Coupling to Iron and Carbon

The Applied Geochemistry group at the Institute of Earth and Environmental Sciences, University of Freiburg (Germany), invites applications for a 3-year PhD position (70 % part-time).

Im Folgenden finden Sie Informationen über die Anforderungen der Stelle, die erwartete Erfahrung des Bewerbers und die dazugehörigen Qualifikationen.
Project Background

Sulfur cycling is a key yet understudied aspect of wetland biogeochemistry. In oxygen-limited environments like peatlands and the Wadden Sea, sulfate rapidly transforms into sulfide, which interacts with iron minerals and influences carbon cycling. Due to the instability of sulfur compounds, conventional analytical methods often fail to capture these processes.

This PhD project will investigate sulfur redox transformations in wetlands and their links to iron and carbon cycling. The work combines laboratory experiments, analytical method development (HPLC, LC-ICP-MS), and fieldwork in the Black Forest, focusing on sulfur pools and transformations in minerotrophic peatlands.

Tasks & Responsibilities

• Design and conduct laboratory experiments on sulfur cycling
• Develop and apply analytical methods for sulfur speciation
• Acquire and analyze synchrotron-based research data
• Identify and establish field sites in the Black Forest, coordinating with landowners and authorities
• Publish findings in peer-reviewed journals and present at conferences
• Contribute to teaching and supervise laboratory practical courses

Your Profile

• MSc or equivalent in environmental science, geoecology, environmental chemistry, geomicrobiology, or a related field
• Strong motivation for interdisciplinary research
• Collaborative mindset, scientific curiosity, and willingness to travel for fieldwork and networking
• Keen interest in environmental geochemistry and analytical method development
• Excellent English (written and spoken); German knowledge is an advantage
• Driver's license (B) is beneficial

We Offer

• A supportive, creative, and interdisciplinary working environment
• Access to state-of-the-art research facilities in newly equipped laboratories
• Opportunities to present research at national and international conferences
• Close scientific supervision and comprehensive onboarding

The position is limited to three years with remuneration according to E13 TV-L. Xsxvtuf The University of Freiburg particularly welcomes applications from women.
