He earned his MD and completed his pediatric residency training at the University of Hawaii, after which he completed his pediatric nephrology fellowship at Seattle Children’s. Dr. Okamura has an active, NIH-funded, basic science research program that is focused on halting and potentially reversing progressive kidney failure through further elucidation of the pathogenic mechanisms involved in renal fibrosis. Currently, his lab is investigating the role of macrophages in mediating both inflammatory and oxidative pathways and their role in cellular crosstalk with interstitial fibroblasts during chronic kidney injury. His clinical interests include the diagnosis and management of infants, children and adolescents with renal disease, particularly renal vasculitis, hypertension and chronic kidney disease.
