Professor Mireille Toledano trained at University College London and the London School of Hygiene and Tropical Medicine, and obtained a PhD from Imperial College London. She is currently a Fellow of the Higher Education Academy and a co-author of the Oxford Handbook series ‘Epidemiology for Clinicians’.

She is an epidemiologist with wide-ranging interests in the health effects of environmental exposures, with particular focus on environmental-omics exposures in the reproductive period, and early life through to adolescence.  She has substantial expertise in leading the design, set-up and coordination of new large cohort studies including the Breast Milk, Environment, and Early-life Development (BEED) study, a child cohort SCAMP (, Study of Cognition, Adolescents and Mobile Phones, a secondary school cohort study of mobile phone use and neurocognitive and behavioural outcomes with biological samples) and an adult cohort COSMOS (, COhort Study on MobileS, an international cohort study of adult mobile phone users).

She also has extensive experience of working with large routine health datasets and spatial epidemiology such as births, deaths and hospital admissions. Her work in this field has included national studies of adverse birth outcomes and water disinfection by-products, waste incineration, and air and noise pollution, as well as investigations of adult cancers near overhead power lines, and childhood cancers in proximity to mobile phone base stations.

She is a member of a number of national and international advisory committees, including the Committee on Medical Aspects of Radiation in the Environment (COMARE), the Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT) and the UN FAO/WHO Joint Meeting on Pesticide Residues (JMPR). She is also Chair of the European Chapter of the International Society of Environmental Epidemiology (ISEE) and currently serves on the Editorial Board of Environmental Epidemiology.
