Overview

Dr. Olga Charnaya is an assistant professor of Pediatrics at the Johns Hopkins University School of Medicine. She specializes in pediatric kidney transplantation but provides care for children with kidney disease of all types including hypertension, chronic kidney disease, dialysis, hematuria, and proteinuria. Dr. Charnaya completed her undergraduate degree at the University of Maryland in College Park, and a Master’s degree in Microbiology and Immunology at Georgetown University. Subsequently, she matriculated at the Ben-Gurion University of the Negev to complete her medical degree. Her residency training was completed at University of Maryland Medical Center where she also served as chief resident. Her subspecialty training in Pediatric Nephrology was completed at Children’s National Medical Center, after which she joined the faculty at Johns Hopkins in 2017. In addition to providing clinical care, Dr. Charnaya is pursuing a Ph.D. in clinical investigation at the Bloomberg School of Public Health, and is actively engaged in clinical research to improve outcomes for pediatric kidney transplant recipients. Specifically, Dr. Charnaya’s research is studying ways to incorporate high-resolution tissue typing into deceased donor kidney allocation using computational modeling to improve immunological matching while preserving pediatric priority and equity (racial and geographic) in access to transplantation. Research Summary Dr. Charnaya’s primary research focus is pediatric kidney transplantation. She has several ongoing research endeavors, including exploring how to implement eplet mismatch analysis in pediatric kidney transplantation, reducing racial and ethnic disparities in pediatric kidney transplantation, and studying the response of pediatric transplant recipients to the COVID-19 vaccine. Dr. Charnaya leads one of the division quality improvement initiatives to optimize care of children with nephrotic syndrome, which is a collaborative effort with eight other children’s hospitals. In 2020, she received the KL2 Clinical Research Scholars Award to support her research and allow her to complete a doctorate in clinical investigation at the Johns Hopkins Bloomberg School of Public Health.
