Dr Mireille B. Toledano is a Reader in Epidemiology at Imperial College London and an investigator of the MRC-PHE Centre for Environment and Health specializing in environmental and spatial epidemiology.

She has extensive expertise in the design and set up of large prospective cohort studies including COSMOS, SCAMP, and BEED. Much of her work to date has focused on early life environmental exposures such as water disinfection by-products, air pollution/noise, non-ionizing radiation epidemiology, and waste incineration, including assessment of environmental exposure at individual level through questionnaire data, biomarkers, and metabonomic profiling. She also has a special interest in spatial epidemiology and the use of routinely collected data and GIS for national small area health studies.
