Dr. Julia Knight is a senior investigator at the Lunenfeld-Tanenbaum Research Institute. She is an epidemiologist and a Professor in the Dalla Lana School of Public Health at the University of Toronto.
Most of Dr. Knight's work has focused on understanding more about the causes and development of breast cancer. Studying breast cancer development led her to an interest in studying breast and other pubertal development in girls. Dr. Knight is also studying how factors even earlier in life can affect later health as part of the Ontario Birth Study, an ongoing study of pregnancy and child health where she co-led the development of the child follow-up component, OBS Kids. She is currently using this study to evaluate potential changes in child developmental outcomes before and after the onset of the COVID-19 pandemic.
