John Kheir is an Associate Professor of Pediatrics at Harvard Medical School and a Senior Associate Cardiologist in the Department of Cardiology at Boston Children’s Hospital. He co-founded and leads the Translational Research Lab within the Heart Center, focusing on oxygen deprivation solutions and critical care innovations.

• Education: University of Virginia (Undergraduate and Medical School), Cincinnati Children's Hospital (Internship), Cincinnati Children's Hospital (Residency), Boston Children's Hospital (Fellowship).

His research spans oxygen delivery systems, congenital heart disease, and critical care metrics. Notable work includes injectable oxygen microparticles, machine-learning models for ICU risk prediction, and hemodynamic monitoring tools. Recent publications explore hemorrhagic shock resuscitation, social determinants of ECMO outcomes, and pediatric sedation protocols.

Key clinical interests include postoperative cardiac care, hypoplastic left heart syndrome, and innovative diagnostics. His lab develops real-time oxygen delivery devices and investigates neurological injury prevention during circulatory arrest.
