Martin Wagner is a biologist interested in what plastics and plastics-associated chemicals do to freshwater ecosystems and human health. To study this, he works at the interface of ecology, toxicology, and chemistry. In 2013, Martin received his PhD degree from the Goethe University Frankfurt am Main for his research on endocrine disrupting chemicals leaching from plastic food packaging. Then, Martin became head of the research group Bioanalytical Toxicology at Goethe University, which focused on toxicity removal during advanced wastewater treatment in several European projects as well as freshwater microplastics. Since 2017, Martin is an associate professor for Environmental Toxicology at the Norwegian University for Science and Technology in Trondheim, where he continues his research into endocrine disrupting chemicals and plastic pollution.
