Research Abstract
Dr. Obi studied medicine at Yamanashi Medical University in Japan and also obtained his PhD degree from Osaka University Graduate School of Medicine, Japan. He is a Fellow of the Japanese Society of Internal Medicine (FJSIM), a Japanese-board certified nephrologist/transplant physician, and a Fellow of the American Society of Nephrology (FASN). Since he joined Dr. Kalantar's research team at UC Irvine in September 2014, he has published >15 papers with his name under the first author in several high-impact, peer-reviewed journals.
