Sonia Grandi, PhD, is a Scientist at SickKids Research Institute and an Assistant Professor at the University of Toronto in the Division of Epidemiology at the Dalla Lana School of Public Health. She completed her PhD in Epidemiology at McGill University in the Department of Epidemiology, Biostatistics, and Occupational Health. Her dissertation focused on the long-term consequences of pregnancy complications on maternal health.

She completed her postdoctoral fellowship at the Eunice Kennedy Shriver National Institutes of Child Health and Human Development at the National Institutes of Health. Her work focused on the consequences of pregnancy complications on maternal mortality and preconception use of medications on reproductive outcomes in couples attempting to conceive.


Dr. Grandi studies the short- and long-term influence of preconception and perinatal exposures on the health of mothers and children. Her research interests include pregnancy complications, prediction modeling, methods in perinatal and pediatric epidemiology, cardiometabolic health of mothers and infants, and the safety of drugs taken during pregnancy in women with chronic conditions. She has expertise in longitudinal and survival analyses, prediction modeling, and the use of administrative health data.

She has received personal and project funding from the Canadian Institutes of Health Research and the Fonds de recherche du Québec – Santé to examine the safety of levothyroxine in women with subclinical hypothyroidism and the contribution of pregnancy complications to the prediction of cardiovascular disease in women.
