Florian Leese

Doctoral Researcher in eDNA-based biodiversity time series in rivers A PhD opening is available in the Aquatic Ecosystem Research group led by Florian Leese at the University of Duisburg-Essen (Essen campus, Germany). The project, TrendDNA 2.0 , is funded by the Umweltbundesamt / German Environment Agency and focuses on reconstructing long-term river biodiversity trends using archived samples from the German Environmental Specimen Bank. The research combines environmental DNA (eDNA), biodiversity monitoring, freshwater ecology, and time-series analysis. Two case studies are highlighted: an eDNA-based early-warning system using high-frequency autosampler samples from a River Rhine monitoring station and monthly suspended particulate matter samples; and identifying drivers of biodiversity change by linking eDNA with chemical data, including non-target screening, and Water Framework Directive (WFD) monitoring data. Applicants should hold a Master’s degree in biology, ecology, environmental sciences, bioinformatics, or a related field. The post also asks for hands-on molecular lab experience, R/Python skills, and strong curiosity about time-series analysis. The team is described as collaborative and experienced in eDNA work, with close exchange with the Environment Agency / German Specimen Bank and interaction with partners including Senckenberg Nature Research and the Leibniz Institute of Freshwater Ecology and Inland Fisheries. Funding details: TV-L E13, 65% position, for 3 years. Start date is as soon as possible. Deadline: 11 November 2026. Interested candidates should read the official announcement linked in the post and follow the application instructions there.
