Bio
To provide the highest level of medical care, I dedicated to enhance clinical practice, education, and research at Kameda Medical Center. I graduated from Kyushu University School of Medicine in 2006. Following my graduation, I completed my initial training at St. Mary’s Hospital and internal medicine training at the Saiseikai Fukuoka General Hospital before joining the Department of Pulmonology, Kameda Medical Center. In September 2023, I became the Director of the Department of Pulmonology and concurrently serve as the Chairman of Internal Medicine at Kameda Medical Center. I hold a Doctor of Medicine degree and work as a researcher in the Department of Public Health, the Graduate School of Medicine, Osaka Metropolitan University. My research focuses on respiratory infections and vaccines. I also serve as an Associate Editor for Human Vaccines & Immunotherapeutics and a member of the Editorial Board for Scientific Reports.

Research Program
