Dr. Till's research interests include children’s environmental health and understanding both protective and risk factors for cognitive decline following insult to the developing brain. Current work is focused on testing the effects of early-life exposure to fluoride on thyroid hormones and child neurodevelopmental outcomes. Her team works with three different population-based cohorts to understand how environmental chemicals are implicated as underlying risk factors for emerging morbidities in childhood, including ADHD. Her team has published several studies focused on the measurement of fluoride exposure in pregnancy, the endocrine-disrupting potential of fluoride, and the impact of fetal exposure to fluoride on child intellectual abilities and behavioural problems. Her research continues to attract the attention of policy-makers, scientists, advocates, media, and lawyers for its relevance to public health.
