Fields of expertise
MissionMy core expertise is in cell biology and environmental toxicology. Linking cell biology and environmental toxicology is a powerful combination for deriving information regarding routes and risks of exposure of life forms to chemical and other stressors and for developing concepts to protect the ecosystem and sustain natural resources. The main focus of my research is on the freshwater environment and on fish or single-cell organisms (such as algae) as experimental models, and on man-made chemicals and products, naturally occurring elements, biologically derived toxins or particles as stressors. Expanding on my education in biology and environmental science, I take an interdisciplinary approach to research and teaching. Major stations of my life so far are: 2008-today Head of Department of Environmental Toxicology (Eawag, Dübendorf, Switzerland) 2010-today Adjunct Professor, EPFL (Switherland) 2007-today Lecturer for Environmental Toxicology (ETHZ, Switzerland) 2003-2007 Head of Department of Cell Toxicology (UFZ Helmholtz Centre for Enviromental Research, Leipzig, Germany) 2001-2003 Junior Research Group Leader (UFZ, Leipzig, Germany) 1997-2001 Postdoctoral Research Fellow (University of Waterloo - Canada and UFZ, Leipzig, Germany) 1994-1997 PhD Enviromental Science (University of Waterloo, Canada) 1994 Diploma Biology (University of Hohenheim and Martin Luther University, Germany)
