Dr. Barbra de Vrijer is a maternal-fetal medicine (MFM) specialist, clinician-scientist, and educator whose work focuses on improving outcomes for high-risk pregnancies through both clinical innovation and interdisciplinary research. She is currently the Division Head of Maternal-Fetal Medicine at London Health Sciences Centre and an Associate Professor in the Department of Obstetrics & Gynaecology at Western University. She also holds appointments as an Associate Scientist at both the Children’s Health Research Institute and the Lawson Health Research Institute.

Since joining the MFM team in London in 2006, Dr. de Vrijer has developed a robust clinical practice and led several innovations in maternal care. In 2011, she co-founded the "MY" Clinic (Maternal & You) with Dr. Debbie Penava, a specialized multidisciplinary clinic dedicated to optimizing pregnancy outcomes in individuals with obesity. The clinic integrates prenatal health services, ultrasound, labour and delivery planning, and postpartum follow-up through personalized care pathways.

 Her research focuses on the abnormal uterine environment and its effects on fetal development, with particular emphasis on maternal obesity, placental health, inflammation, and the maternal microbiome. Dr. de Vrijer leads a multidisciplinary Pregnancy Research Group and continues to advance translational research that connects clinical findings to improved maternal-fetal outcomes. 

Dr. de Vrijer is also a Co-Investigator on the PARTUM Trial (Postpartum Aspirin to Reduce Thromboembolism Undue Morbidity), a major national clinical trial investigating the effectiveness of low-dose aspirin in preventing postpartum venous thromboembolism (VTE) among at-risk patients. The trial is led by Dr. Krista Skeith, the Principal Investigator, and is funded by the Canadian Institutes of Health Research (CIHR) with a total grant of around $4,600,000. This significant study represents an important step toward evidence-based postpartum care and reducing maternal morbidity in Canada.
 
In addition to her research and clinical leadership, Dr. de Vrijer is actively involved in mentoring medical students, residents, and fellows, and contributes to the ongoing development of maternal-fetal medicine as both a clinician and an educator.
