Professional Activities
Dr. Sharon Bartosh is professor (CHS) and chief in the Division of Nephrology, a role she began in 1998. She previously served as medical director of pediatric kidney transplantation from 1998 to 2021. In her role as an advocate for equity for pediatric kidney transplantation candidates, she has been on the board of directors of the United Network of Organ Sharing (UNOS) and held leadership positions and been a councilor of the American Society of Transplantation (AST). She currently serves on the American Society of Pediatric Nephrology (ASPN) Foundation Board and was honored with the inaugural ASPN Service Award.

Locally, she received the UW Physician Excellence Award and the Pediatric Resident Teaching Award.
Clinical Interests
An active clinical provider, Bartosh sees patients around Madison and regionally. She treats children with renal failure who need dialysis and transplantation. Other clinic interests include growth in children with renal disease.
Research Interests
Bartosh’s research has focused on growth pre- and post-transplantation, long-term outcomes after pediatric kidney transplantation, and novel immunosuppression regimens to allow corticosteroid minimization/sparing in pediatric kidney transplantation. She is the University of Wisconsin site PI for Chronic Kidney Disease in Children (CKID), an NIH-funded, multicenter, observational, prospective cohort of children, adolescents, and young adults with a history of mild to moderately impaired kidney function. The study, which has been funded by the NIH since 2003, includes more than 50 pediatric nephrology centers across the U.S. and Canada and has enrolled more than 1,100 children with mild to moderate CKD. Now in its fourth cohort, the study aims to understand the risk factors for decline in kidney function in childhood and young adulthood, the impact of childhood CKD on the development of cardiovascular disease, the trajectories of markers of metabolic bone disease, and the successful transfer from pediatric to adult nephrology care. Additionally, Bartosh is the site PI for the CureGN study, or the Cure Glomerulopathy Network, which is an NIH-funded, multicenter, observational study focused on glomerular diseases, specifically minimal change disease, focal segmental glomerulosclerosis, membranous nephropathy, and IgA nephropathy with the aim to improve understanding, diagnosis, treatment, and outcomes for children with these chronic kidney conditions.
