Environmental Chemistry of Biomolecules
My research focusses on determining chemical information to evaluate water quality and to protect human health and ecosystem functioning. This information is crucial for public authorities to manage water resources especially as we are facing growing inputs of bioactive chemicals with adverse environmental effects. My work is rooted in environmental and analytical chemistry of aquatic enzymes, natural toxins, and micropollutants. I investigate the environmental behavior of these molecules to define the exposure side of human and ecological risk assessment. Specifically, my research focusses on the occurrence and persistence of these bioactive substances in surface waters. My group has built an expertise for analytical solutions to study site-specific damage of biomolecules of varied complexity and for environmental transformation processes. My aim is to elucidate how long-lived these biomolecules are in aquatic systems and which transformation products are formed with a particular focus on photochemical and enzymatic processes.
