Stefan studied biology at the University of Constance, Germany, with a focus on developmental neurobiology, immunology, behaviour biology and ecotoxicology. During his PhD he focused on the issues of drinking water treatment of cyanobacterial-loaded surface waters and the consequences for human health. During his international studies Stefan investigated the efficiency of treatment techniques in several drinking water treatment plants in Switzerland, Germany and Australia. After completing his PhD he coordinated the toxicological section of the EU project Toxic and Bioactive PEPtides in CYanobacteria (PEPCY) with partners in several European countries.
Stefan has several years of experience in the CRO industry. His field of expertise covers ecotoxicology, toxicology, biodegradation, analytical chemistry and also regulatory know-how (agrochemicals, biocides, chemicals and pharmaceuticals). He previously worked as a study director, team coordinator, team leader, department head and GLP test facility manager in academia and industry.
Stefan joined IES Ltd in 2014 as COO. On the 1st September 2017 Stefan was announced as the CEO of IES Ltd.
Wolfgang has a PhD in chemistry from the Technical University of Munich, Germany, and two decades of experience as a study director for e-fate studies in contract research organisations (RCC/Harlan, IES).
In his thesis he investigated the formation of bound residues of plant protection products. He has intensive experience in the design, conduct and interpretation of the full range of e-fate studies, especially adsorption/desorption studies and degradation and metabolism in soil, aquatic systems and surface water.
Wolfgang’s expertise covers different types of chemicals and he has managed the delivery of testing programs which meet all aspects of regulatory requirements for product registration. As Chief Scientific Officer he is responsible for maintaining the top scientific level of IES.
