Dr. Marwa Mansour is a Pediatric Critical Care Physician Specializing in the care of critically ill infants and children, with a focus on extracorporeal life support (ECMO), acute respiratory failure and neurocritical care. Her scholarly work centers on optimizing nutritional support in the pediatric intensive care unit (PICU) and exploring the role of the gut microbiome in critical illness outcomes.
She maintains an active research and teaching portfolio, frequently presenting at national meetings and contributing to peer-reviewed publications. Dr. Mansour is also deeply committed to medical education and mentorship, leading curriculum development and supporting trainees and junior colleagues in their professional growth.
Personal Statement
I am deeply committed to providing thoughtful, evidence-based care to critically ill children and their families. I believe that pediatric critical care is not only about advanced technology and physiology, but also about presence, clarity and compassion during some of the most difficult moments in a family’s life. I strive to communicate openly, listen actively and partner closely with families so that care decisions reflect both medical expertise and their values.
My approach integrates scientific rigor with individualized care. I am particularly passionate about optimizing nutrition and supporting recovery in the PICU, translating research into practical strategies that improve outcomes. I also value education and mentorship and am dedicated to supporting trainees and colleagues in their growth into compassionate, skilled physicians.
Outside of medicine, I enjoy spending time with family and friends, engaging in reflective writing, exploring nature and exploring creative outlets that help me stay grounded and balanced. These experiences enrich my perspective and strengthen my commitment to serving my patients and community with integrity and empathy.
