About Me

Research Interest
Wastewater is one of the most information-rich and dynamic waste streams of our society. My interests lie in source typing and tracking of water-borne pollutants such as personal care products, pharmaceuticals and illicit drugs in both the built and natural environment. I combine full scale measurements, modeling (deterministic and stochastic) and laboratory experiments. Furthermore, I develop new measurement devices and work flows to gain unprecedented insight into pollutant dynamics and the spatio-temporal variability of environmental variables.


New devices
Transportable high-resolution mass spectrometry; floatable sensor platforms; application of passive samplers in highly dynamic water systems

Wastewater-based epidemiology
SARS-CoV-2; sampling and monitoring design; processes in sewers; transformation of parent and metabolites in sewers (lab and full scale experiments)

Wet-weather discharges
Micropollutants from urban areas; separate and combined sewers; prediction based on land use

Source control
Quantification of hospital wastewater; comparison to other sources (households)

Pollutant fluxes in natural water bodies
Micropollutant removal; modeling and monitoring concepts; resource allocation
