Faculty Bio

Dr. Smith completed a combined MD/PhD at the University of Western Ontario in 1992 under the supervision of Dr. John Patrick.  He subsequently obtained his FRCSC in Obstetrics & Gynecology at Queen’s University in 1997 and completed sub-specialty training in Maternal-Fetal Medicine at the University of Toronto in 1999 before joining the faculty at Queen's. 

Dr. Smith is a member of the Maternal-Fetal Medicine Division and is the Professor and Head of the Department of Obstetrics & Gynecology at Queen’s University and is cross-appointed to the Department of Biomedical and Molecular Sciences and Imaging Services. 

Dr. Smith divides his time between high-risk obstetrics, clinical/basic science research and as the director of the Clinical Investigator Program for the School of Medicine, Faculty of Health Sciences at Queen’s University.

Research Interests

Dr. Smith runs the Queen's University Perinatal Research Unit which has a basic science laboratory and a clinical research/clinical trials group. The current focus of both his basic and clinical research is on adverse obstetrical events, specifically related to the etiology, outcomes and potential therapies for pre-eclampsia.

Current research themes include:

  1. Examining adverse pregnancy outcomes as a marker of future maternal health. Dr. Smith has developed The MotHERS Program (Mothers Health Education, Research and Screening) and its website ( to improve maternal health and outcomes.
  2. Exploring the molecular, haemodynamic and morphological effects of carbon monoxide gas inhalation on the utero-placental environment. Dr. Smith has active research projects aimed at elucidating the role of carbon monoxide exposure and maternal risk for, and symptomatic presentation of pre-eclampsia.


Research Funding History
