Brief Biography

Dr. Karel O’Brien is a Staff Neonatologist at Mount Sinai Hospital and Associate Professor of Paediatrics
at the University of Toronto. She is a clinical teacher at a busy perinatal center that specializes in fetal
diagnosis. She has trained in Clinical Epidemiology and Health Care Research. Her research has focused
on improving the outcomes of preterm infants and infants born with complex needs such as congenital
diaphragmatic hernia using different methodologies including cohort studies, randomized controlled
studies and epidemiological research. She has also mentored several trainees in the critique, design and
conduct of unbiased clinical studies. Her current research has focused on Family Integrated Care, a
model that changes how we deliver care to families and their infants in the NICU, and she has recently
completed an international trial of this model of care.
