Adeline (Wei Li) Koay, MBBS, MSc, completed a pediatric residency at the University of Texas Medical Branch and a pediatric infectious diseases fellowship at Johns Hopkins University. She received a medical degree from the University of Melbourne in Australia, and a Masters in Science (Bacteriology) from the University of Technology in Sydney, Australia.

Dr. Koay’s clinical expertise and interests focus on the general pediatric infectious diseases and the care of children and adolescents with HIV. Her research interests lie in patient-oriented and implementation science research to better understand the gaps in HIV prevention, and develop interventions to optimize HIV treatment outcomes for children and youth living with HIV. She was a Mid-Atlantic CFAR (Center for AIDS Research) Consortium Scholar in 2021-2022, during which time she studied the impact of rideshare services on health outcomes of pediatric and adolescent patients receiving care for HIV. Dr. Koay has also received a DC CFAR Pilot Award and CTSI-CN Pilot Award to study the relationship between the gut microbiome and inflammation in infants born to women living with HIV.
