About James L Wynn

My name is James Wynn, MD, and I work as a professor of pediatrics and pathology, immunology and experimental medicine in the University of Florida Department of Pediatrics Division of Neonatology. I earned my medical degree from UF in 2002. I then completed an internship and residency in pediatrics and a subsequent fellowship in neonatal- perinatal medicine at UF. Prior to joining UF Health in 2015, I served as faculty at both Duke University and Vanderbilt University. I am proud to have been selected as the Richard Rivas, MD Memorial Great Teacher Award by the leadership of the Specialty Review in Neonatology in 2022. I have published over 100 peer-reviewed manuscripts, reviews, book chapters and editorials. I have served as reviewer for the NIH, the Bill and Melinda Gates Foundation, USAID and over 35 scientific journals, including Pediatric Research where I was an associate editor from 2016-2022. I am pleased to have mentored over 30 trainees ranging from undergraduate to post-doctoral level.

My inspiration to become a doctor arose from my fascination of how the human body functions and my desire to help others live the healthiest lives possible. During medical school, taking care of children brought me tremendous satisfaction and fulfillment. While in my pediatric training, I fell in love with neonatology. In the neonatal ICU, I am grateful and honored to have the privilege of helping premature and sick babies and to support their families though very challenging times. I strive to partner with families and staff to provide the most up-to-date, compassionate and humanistic care possible.
