Dr. Adre du Plessis has focused his clinical and research interest exclusively on the immature brain, understanding its normal development, as well as the causes and consequences of abnormal brain development. Born in Cape Town, South Africa, Dr. du Plessis received his medical degree from the University of Cape Town, South Africa, and completed his residency at Groote Schuur Hospital in Cape Town. He trained under the ‘father’ of neonatal neurology, Dr. Joseph Volpe, first at St. Louis Children’s and then at Boston Children’s Hospital. Dr. du Plessis developed the Neonatal Neurology Program as well as the Neurocardiology Program at Boston Children’s and Harvard’s Longwood medical centers, both first in their field anywhere. Since 2010, he has been director of the Prenatal Pediatrics Institute at Children’s National in Washington, DC. He has a longstanding track record of mentoring in the field and is currently Co-Pi with Catherine Limperopoulos, PhD, on a T32 Training Grant (NICHD 1T32HD098066). Over the past 25 years he has led a team that has developed multimodal neuromonitoring devices that allow an unprecedented depth of continuous bedside inquiry into both the systemic support systems, as well as autoregulatory systems intrinsic to the brain. This approach has allowed unique insights into the immature brain’s responses to critical illness, and has provided an invaluable framework for the training of young clinical investigators into the complex pathophysiology of the immature human brain.
