The Division of Nephrology provides comprehensive care to all infants, children and adolescents with kidney disease who live in Western New York and northern Pennsylvania. We are experts in clinical care, research and education.

Education and Training

All faculty members in our division are physicians board-certified in pediatric nephrology. As such, they provide leadership in medical education and in basic science and clinical research.


Current research focuses on renal impairment in the overweight, along with strategies to reverse it.
