Dr Koen Oorts obtained his masters degree in environmental engineering and his Ph.D. in applied biological sciences from the University in Leuven (Belgium).

After his Ph.D., Koen worked as a postdoc researcher at the Division for Soil and Water Management at the same university on research projects related to metal bioavailability and toxicity in soils. In 2009, he was a co-founder of ARCHE Consulting. 

His main expertise area comprises the fate and behavior of substances in the environment, terrestrial ecotoxicology and the development of predictive models for bioavailability and toxicity of contaminants in soils and their implementation in various regulatory frameworks.
