Her research bridges reproductive endocrinology, infertility, and epidemiology, focusing on the interplay between endocrine disruptors, perinatal outcomes, and women's health.

Her work spans population-based cohort studies like the MIREC Study and CLSA, analyzing environmental chemical exposure, digit ratios, and fertility metrics. Recent projects examine gestational carriers, polycystic ovary syndrome, and endometriosis through clinical and policy lenses. She mentors students such as Emily C. Richmond and Aisha Nathoo, integrating research into medical education via the Queen’s UGME Critical Enquiry course.

Key article themes include reproductive epidemiology, maternal-fetal health, and infertility interventions, with subtopics like gestational diabetes, opioid use in pregnancy, and stroke risks in endometriosis. She advocates for patient-centered care and has contributed to national guidelines on fertility preservation and obesity in pregnancy.
