Milo de Baat is Assistant Professor in Water Quality & Ecotoxicology at the Department of Freshwater and Marine Ecology of the Institute for Biodiversity and Ecosystem Dynamics at the University of Amsterdam. He previously worked as a scientific researcher in the Chemical Water Quality & Health group at KWR Water Research Institute. Milo's research explores how chemical pollution affects the health of aquatic ecosystems. Water is essential to life, but the increasingly complex chemical burden that human activities impose on freshwater and marine environments negatively impacts the biodiversity and functioning of aquatic ecosystems and threatens the provision of clean and safe water for human use and consumption. By combining innovative sampling methods and effect-based toxicity assessment, Milo's research aims to unravel the complexity and toxic effects of chemical mixtures in the environment. By aligning these findings with knowledge of biodiversity and ecosystem functioning, he strives to quantify the limitations that chemical pollution imposes on environmental health in a variety of aquatic ecosystems.
