Prof. Dr.-Ing Stephan Wagner is the head of the Institute for Analytical Research at the Hochschule Fresenius University of Applied Sciences in Idstein, Germany. He is an expert in the analysis and fate of anthropogenic materials such as tire and road abrasion particles, micro- and nanoplastics, nanomaterials as well as organic trace contaminants in the (urban) water cycle. 

Stephan graduated from Technische Universität Dresden, Germany in waste and contaminated site management and received his PhD in mine water treatment in 2011 from Brandenburgische TechnischeUniversität Cottbus, Germany. Before joining Hochschule Fresenius in Idstein in July 2022, Stephan worked at several research institutions in Germany and Austria as Postdoc and research group leader. He has been involved in numerous national and international research projects related to microplastics in the water cycles, engineered nanomaterial and tire wear emissions. He is active in several working groups of the German Chemical Society (Working groups on microplastics, PMT substances and nanomaterials in food) as well as in standardization activities of the German Institute for Standardization (DIN) for microplastic sampling and spectroscopic analysis.
