Dr. Farzana Perwad is a specialist who cares for children with kidney disease, including those requiring dialysis and kidney transplant. Her expertise includes evaluating and treating chronic kidney disease in children, nephrotic syndrome (a disorder that causes excessive excretion of protein in the urine), kidney stones, urinary tract infections, and kidney or urinary tract abnormalities that were present at birth. Her research focus is to understand the molecular mechanisms of regulation of phosphorus and vitamin D metabolism in the setting of chronic kidney disease.
