Research Interests
My research focuses on understanding sediment-water interactions in aquatic systems and their influence on nutrient and pollutant dynamics. Key areas of interest include sediment biogeochemistry, paleolimnology, eutrophication, lake restoration, and the impact of emerging pollutants.
Current Project
Fostering European lakes restoration by nutrient removal, recovery, and reuse: integrated catchment and in-lake scale approach (FERRO)
FERRO, funded by the European Union, aims to provide sustainable solutions to eutrophication in lakes by integrating nutrient recovery and reuse in agriculture, supporting both food security and ecological health. As the Project Coordinator, I oversee a multidisciplinary team working on four innovative, nature-based, circular solutions tailored to restore lakes with either external or internal nutrient loading challenges. FERRO consists of 10 work packages, with UFZ leading four: the first is project management; the second reviews past lake restoration efforts in Europe with a focus on cost efficiency; the third involves applying phosphorus removal and recovery at a eutrophic drinking water reservoir, with potential reuse of phosphorus as fertilizer in agriculture; and the fourth focuses on transferring FERRO solutions to other EU countries. Learn more about the project at FERRO Project Website.
Previous Project
Rapid, event-driven shortcuts between benthic nutrients and phytoplankton in inland and coastal waters (EventNut)
The DFG-funded EventNut project was conducted in collaboration with the University of Rostock, Department of Aquatic Ecology, and the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB). The project focused on investigating the link between sediment nutrient release and phytoplankton physiology using high-frequency, in-situ monitoring methods in shallow lakes. We successfully demonstrated the use of in-situ SRP (soluble reactive phosphorus) analysis as a reliable tool for capturing rapid nutrient dynamics. Learn more about the project at EventNut Project Webpage.
Contact and Collaboration
I welcome opportunities for collaboration and knowledge exchange with fellow scientists across disciplines. Additionally, I am eager to support the next generation of researchers. Students interested in internships, bachelor’s, or master’s theses are encouraged to reach out to discuss potential projects and opportunities to contribute to ongoing research.
