# Peter Grathwohl

Peter Grathwohl (born 1958) is a German geologist and expert in hydrology and environmental processes. 1996 he was appointed a full professor of hydrogeochemistry at the University of Tübingen, Germany. Since 2014, he has been vice-president of research of the University of Tübingen.

## Life

Grathwohl was born in Sigmaringen, Germany. He studied Geology at the University of Tübingen. After his diploma 1985 he finished his doctorate in 1988. From 1989 to 1990, he worked as a postdoctoral researcher at Stanford University. In 1990 he returned to Germany and built up a research group and laboratories for geochemistry at the Center of Applied Geosciences, Tübingen University, and in 1996 he was appointed to the rank of a full professor of hydrogeochemistry. From 1997 to 2000, he served as secretary of the section “hydrology and chemical processes” of the European Geophysical Union. 1997-2003 he was member of the scientific advisory committee for soil protection of the Federal Government of Germany and since 2005 he has been in the soil protection commission of the German Federal Environmental Protection Agency. From 2006 to 2010 Grathwohl served as dean of the geoscience faculty of Tübingen University, and was vice-dean of the new-created faculty of sciences from 2010 to 2014. Since 2014 he has been vice-president of research of Tübingen University. In 2015, he was elected as a member of the senate of the German Research Foundation (DFG). 2006-2010 he chaired the section of hydrogeology of the German Geological Society. 2000-2010 he was chair of the standardization committee "Leaching Tests" in the Deutsches Institut für Normung (German Institute for Standardization, DIN, NAW).

## Research

Grathwohl´s research interests focus on fate and transport of persistent organic pollutants in water, air, soils, and sediments. In applied geosciences he worked on contaminated site assessment and groundwater remediation techniques and developed standards for aqueous leaching of waste materials and the monitoring of atmospheric deposition of persistent organic pollutants. In his career, he managed numerous national and international joint research projects funded by the European Union, the German Federal Government and the German Research Foundation.
