Ryan is currently serving as a chief resident and a clinical instructor in pediatrics after completing his residency at Stanford Lucile Packard Children’s Hospital. Prior, he obtained his undergraduate degree in anthropology at the University of Notre Dame and his Masters of Science in Global Health at Duke University. In graduate school, he worked at the Duke Global Health Institute in the lab of Dr. C. S. Meade exploring the co-occurrence of HIV and substance use disorders both domestically and internationally. His thesis work brought him to Cape Town, South Africa for several months to lead a joint study in conjunction with Duke University, the University of Cape Town, and the City of Cape Town exploring HIV prevalence, sexual risk behaviors, and mental health among methamphetamine users seeking treatment at a city rehabilitation clinic. He completed his MD at Georgetown University School of Medicine where he was a coordinator of the medical school asylum clinic for refugees and later served on the national medical student advisory board for Physicians for Human Rights. In addition to South Africa, over the course of his academic career, he have worked in research or clinical capacities in Senegal, Cameroon, Lesotho, and Tanzania. His current research interests are in addressing both local and global healthcare disparities in pediatric hematology/oncology.
