Bio

Dr. Humphrey is a physician-scientist with board certification in Internal Medicine, Pediatrics, and Adult Infectious Diseases. He is dedicated to improving the delivery of HIV care in resource-constrained settings, with a specific focus on the prevention of mother-to-child transmission of HIV. From 2016-2019, Dr. Humphrey served as the Pediatric Team Leader for the Academic Model Providing Access to Healthcare (AMPATH) in Kenya. Using implementation science and mixed methods approaches, Dr. Humphrey investigates the social-ecological and structural barriers influencing cascade outcomes for vulnerable populations affected by HIV, including pregnant and breastfeeding women, children and adolescents. Additional areas of focus include HIV drug resistance and the impact of antiretroviral treatment on pregnancy outcomes and infant growth and development. Much of his current research is conducted at AMPATH and in collaboration with the East Africa International Epidemiologic Database to Evaluate AIDS (IeDEA) consortium. His research is supported by an NIH K23 award entitled "Adaptation, execution and evaluation of a differentiated service delivery model for PMTCT" (#1K23HD105495, see: https://reporter.nih.gov/project-details/10252106).
