Anna Sokol studied geology at the University of Münster, Germany) with focus in Mineralogy/Geochemistry. She received her doctoral degree (Dr. rer. nat.) from the Institute for Planetology at the University of Münster, Germany. During her doctoral studies she worked on questions concerning the early solar system evolution by studying meteorites. Early 2009 she joined the FEhS-Institute and since December 2020, Anna Sokol is the head of the environment department. In her present role she is focusing on research related to iron slag formation, its mineralogy and chemistry as well as the environmental impact when being used in different applications. Finding new application areas for slag based products and monitoring regulations and environmental legislation as well as activities related to the REACH registration are further fields of works.
