Faculty Advisor
 swansonj@email.chop.edu

Jordan Swanson is an attending surgeon in the Division of Plastic Surgery at the Children’s Hospital of Philadelphia with special clinical expertise in cleft, craniofacial, and pediatric plastic surgery. His innovation and research initiatives are focused principally on how surgical care can be better adapted to low-resource settings, through design of clinical devices and techniques, locally-driven leadership and team capability strengthening, and reorienting care pathways appropriate to local contexts and resources. In parallel, these initiatives are also generating insight into less-invasive, patient-directed advances for surgical care delivery in tertiary settings. He previously worked and lived in Nicaragua, collaborating with Operation Smile and the Nicaraguan Ministry of Health to build a joint Comprehensive Cleft and Craniofacial program, and is the primary investigator of the Cirugia Para el Pueblo pilot program to advance the access to and impact of rural surgical care in Nicaragua.
