One Health Toxicology

Marianne Bol-Schoenmakers is responsible for the majority of education activities of the toxicology department of the Institute for Risk Assessment Sciences (IRAS), both within and outside the University. She coordinates various bachelor courses on toxicology and contributes to educating toxicology at the faculties of Biology, Biomedical Sciences, Veterinary Medicine and Geosciences of the UU and at the UCU. She is co-coordinator of the drug toxicity and communication course in the Pharmacy master. Marianne is also involved in the development of the master Health and Environment and in post graduate education on toxicology, and is a lecturer in those programmes. In addition, she is involved in the supervision of bachelor and master students during their practical internships. Finally, she is involved in the development of education on new animal-free test methods to evaluate the risk of chemicals. Education will be developed in context of the NWA-project VHP4Safety, meant for bachelor and master students, as well as PhD-students and professionals in the field.


Marianne puts much efforts into continuous improvement and updating of education, and investigates the use of digital tools to increase student learning outcomes and motivation. Recently, she incorporated the interdisciplinary approach in the development and improvement of education. 


Furthermore, Marianne is chair of the bachelor exam committee of the Veterinary Faculty, and has been member of the Assessment Support Panel of the Graduate School of Life Sciences (GSLS) for several years. Both activities give her the opportunity to increase and apply her knowledge on reliable assessment.


In addition to education, Marianne is involved in research on the adverse effects of various agents including drugs, microplastics, and (environmental) chemicals on the immune system, with emphasis on the gut.
