Professor of Toxicology and Environmental Health; Theme Leader of the Environment and Health Theme
Juliette Legler is Professor of Toxicology and Environmental Health at the College of Health and Life Sciences, Brunel University London. She is also leader of the Environment and Health Theme, a multidisciplinary group of about 60 researchers within Brunel University’s Institute for Environment, Health and Societies. Prior to joining Brunel University London in January 2016, she was employed for over 14 years at the Institute for Environmental Studies, VU University Amsterdam, where she was Deputy Head of the Department of Chemistry and Biology. From 2014-2015 she served as Director of the SENSE Research School for Socio-Economic and Natural Sciences of the Environment, a joint venture of the environmental research institutes of ten Dutch universities. Voted the VU’s Faculty of Earth and Life Sciences Teacher of the Year in 2012, she has taught environmental toxicology at the BSc and MSc level at the VU and coordinated an MSc program in Environmental Chemistry and Toxicology. Her research focusses on the molecular mechanisms of toxicity of chemicals and the effects of chemical exposure on humans and wildlife. An author of about 100 scientific articles and book chapters, she is particularly interested in understanding the role of epigenetics in the long term health impacts of early life exposure to environmental chemicals. Prof. Legler is a European registered toxicologist and was elected Vice President of the Netherlands Society of Toxicology in June 2015.
