Research interests

Dr. Mitra’s research interests include neonatal hemodynamics, oxygenation and perfusion.  His current research projects include a pan-Canadian project on the comparative effectiveness of non-steroidal anti-inflammatory agents (NSAIDs) for treatment of patent ductus arteriosus (PDA) in preterm infants (funded by the Canadian Institutes of Health Research); development of a clinical practice guideline on use of prophylactic NSAIDs for prevention of morbidity and mortality in preterm infants and effect of caregiving interventions on cerebral oxygenation and perfusion in preterm infants.
