Carsten Prasse

Assistant Professor

Research Interests

environmental chemistry, exposome science, water treatment, environmental health

Carsten Prasse’s research is driven by a fascination with water chemistry and a deep concern about the public and environmental health impacts of chemicals present in our water. He investigates the fate of contaminants in the built and natural environment using state-of-the-art analytical chemistry techniques (e.g. high-resolution mass spectrometry) with the focus on identifying transformation products and understanding underlying mechanisms of transformation in the urban water cycle. Prioritizing which compounds are most threatening to human and environmental health is a great challenge given that thousands of chemicals are present in our waters. To tackle this problem, Carsten’s research has recently focused on using concepts and methods from toxicology and public health. This work is interdisciplinary with the goal of developing new methodologies to inform water treatment technology development, comprehensively assess water quality and characterize the drinking water exposome.

Carsten received his Diploma (i.e. Master’s degree) in Geoecology at the University of Bayreuth, Germany, where he studied the pollution of urban soils in Addis Ababa, Ethiopia. Carsten received his PhD in Chemistry at the Federal Institute of Hydrology in Koblenz, Germany. His PhD thesis was honored with the dissertation award of the German Water Chemistry Society. Carsten did his postdoctoral work at the Federal Institute of Hydrology and the University of California at Berkeley, where he investigated the degradation of organic contaminants by advanced oxidation processes and in-situ chemical oxidation with particular focus on the potential impacts on environmental and public health.
