Senior Scientist
Areas of Expertise
- Fate and behavior of emerging contaminants in natural waters
- Exposure analysis of pesticides and biocides in the aquatic environment by field studies and computer modeling
- Development of trace analytical methods for the identification of organic contaminants in ground, surface and waste waters
Selected Current and Recent Projects
- Sources and input pathways of the herbicide glyphosate into surface waters - field measurements and mass flux studies
- Load balance of selected pharmaceuticals and corrosion inhibitors for the lake Constance - a combined approach of measurement and modeling
- Development of a comprehensive screening method for the identification of target and non-target compounds in water samples using liquid chromatography coupled to high resolution mass spectrometry
Anticipated and Planned Research Activities
- Sources and fate of glyphosate in the urban watercycle: from use in urban areas to input into surface water
- Enhancement of the non-target screening approach for the identification of emerging organic pollutants in environmental water samples - method developments and applications
