Wastewater-based epidemiology

Wastewater is one of the most information-rich and dynamic waste streams of our society. My group focuses on quantifying water-borne pollutants such as personal care products, pharmaceuticals and illicit drugs in both the built and natural environment. We combine full scale measurements, modeling (deterministic and stochastic) and laboratory experiments. Furthermore, we 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)

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