Alexandria Ratzki-Leewing

Alexandria Ratzki-Leewing serves as an Adjunct Professor in the Department of Epidemiology and Biostatistics and a Scientist in the Department of Family Medicine at Western University's Schulich School of Medicine & Dentistry. She also directs the Hypoglycemia Research Program within the Diabetes Alliance at the Centre for Studies in Family Medicine.

Her research focuses on real-world diabetes epidemiology, particularly hypoglycemia in type 1 and type 2 diabetes, pharmacoepidemiology, and the development of real-world evidence methods. She investigates health survey design, person-reported outcomes, and the impact of social determinants on chronic disease management in aging populations and marginalized groups.

Recent publications (2018-2023) from studies like iNPHORM (US) and InHypo-DM (Canada) emphasize severe hypoglycemia incidence, risk prediction modeling, and pandemic impacts on diabetes care, contributing to clinical guidelines such as the American Diabetes Association's Standards of Care.

Scientific recognition includes:

• Rising Star Award from the International Diabetes Center (2023)

As Director of the Hypoglycemia Research Program, she leads international collaborations including the large-scale iNPHORM study, which is America's largest prospective investigation on hypoglycemia risk, and serves on advisory boards like the International Hypoglycaemia Study Group.
