Dr. Cozumel S. Pruette is an assistant professor of pediatrics at the Johns Hopkins University School of Medicine. She provides care for children with kidney problems of any type, from microscopic hematuria to kidney transplant recipients.

After graduating with a bachelor's degree in biology from University of North Carolina at Chapel Hill, Dr. Pruette earned a master's degree in neuroscience from Northwestern University in Evanston, Illinois. She earned her medical degree with Southern Illinois University School of Medicine in Springfield, Illinois, and completed her internship and residency at Johns Hopkins University, where she was a chief resident. Dr. Pruette went on to complete a fellowship in pediatric nephrology at Johns Hopkins in 2012. As part of her fellowship training, she received a master's degree in clinical epidemiology from the Johns Hopkins Bloomberg School of Public Health.

Dr. Pruette’s research is focused on improving self-management, patient engagement, transition of care and medication adherence in patients with chronic kidney disease and end-stage renal disease. She leads the pediatric/young adult transition of care program for the Johns Hopkins Comprehensive Transplant Center. Dr. Pruette is the principal investigator in the development and implementation of a peer-mentoring program for adolescents with kidney transplant. She has established national patient and family advisory councils for the North American Pediatric Renal Trials and Collaborative Studies (NAPRTCS) and for the Chronic Kidney Disease in Children (CKiD) Study.

She has been the recipient of numerous research grants, including the KL2 Clinical Research Scholars Award, as well as the Pearl M. Stetler Research Fund Award, multiple awards from the National Kidney Foundation of Maryland, and the NIH NIDDK. more
