Jochem Louisse works as a toxicologist in the Chemical Water Quality and Health team. He studied biology in Wageningen and then did doctoral research at TNO and Wageningen University & Research. During the course of his doctoral research, he developed an approach in which data from in vitro bioassays can be used for the toxicological risk assessment of compounds, by combining them with models which describe the kinetics of compounds in the body. He was awarded several prizes for this work for example, from the American Society of Toxicology (SOT) and the European Partnership for Alternative Approaches to Animal Testing (EPAA). Following post-doctoral work at the Joint Research Centre (JRC) of the European Commission, and a job as a university lecturer in Toxicology at Wageningen University & Research, Jochem joined KWR as a toxicologist in 2017. Here, he works on the assessment of the health risks of compounds on commissions from the drinking water companies, government entities and industry. His research focusses primarily on the application of data from in vitro bioassays in combination with kinetic models, in order to make initial risk assessments of compounds for example, to prioritise compounds for monitoring and water treatment purposes.
