Meet the Minds: Dr. Stephen Matthews explores how our earliest experiences can shape lifelong health
What if the foundations of our health are laid before we are even born?
That question has driven Dr. Stephen Matthews’ research for more than three decades. A Senior Investigator at Sinai Health’s Lunenfeld-Tanenbaum Research Institute (LTRI), Dr. Matthews studies how the environment during pregnancy can influence fetal development and potentially affect the health of the child years or even decades later.
His work spans neuroscience, pregnancy, epigenetics and population health, with a goal of understanding not only how early experiences leave their mark, but how that knowledge could help prevent health problems before they begin.
Dr. Matthews also co-directs the Ontario Birth Study (OBS), a research platform embedded at Mount Sinai Hospital that follows families from early pregnancy through childhood. By combining detailed health information with biological samples collected over time, OBS is helping researchers connect the dots between our earliest environments and future health.
