About Shawn McCandless

Dr. McCandless earned his M.D. at Temple University and completed Pediatric Residency training at the University of Wisconsin in Madison.

He worked as a Paediatric Registrar in Gloucester, England, then as a general pediatrician at the Northern Navajo Medical Center in Shiprock, NM. He then completed a fellowship in Medical Genetics and Metabolism at Case Western Reserve University before joining the faculty of the Departments of Pediatrics and Genetics at the University of North Carolina - Chapel Hill.

Dr. McCandless is now a member of the Genetics faculty at Case and part of the Center for Human Genetics and the Center for Inherited Disorders of Energy Metabolism.


Dr. McCandless is interested in treatment of genetic disorders, focusing his research primarily on management of inborn errors of metabolism and Prader-Willi syndrome.

Particular attention is paid to developing protocols for managing infants with fatty acid oxidation disorders diagnosed by newborn screening, and to long-term outcomes in those patients.
