Kiyohiko Mabuchi, M.D., Dr.P.H.

Biography

Dr. Mabuchi is a special volunteer in the Radiation Epidemiology Branch (REB). He retired from federal service after over 20 years of service as a senior scientist in REB. In that role, he was engaged in epidemiological studies of thyroid disease and leukemia risks following the Chernobyl nuclear reactor accident and the continuing follow-up studies of cancer in the Japanese atomic-bomb survivors.

Dr. Mabuchi received an M.D. from Osaka University Medical School, Japan, and an M.P.H. / Dr.PH. from the John Hopkins University School of Hygiene and Public Health, Baltimore, Maryland. He joined REB in 2000 after serving as Chief of the Department of Epidemiology at the Radiation Effects Research Foundation, Hiroshima, Japan, where he led the long-term epidemiological studies of health effects of radiation exposure in cohorts of atomic bomb survivors and their children. Dr. Mabuchi then served as Deputy Branch Chief from 2002–2014.

He has been a member of several international radiation committees, including the International Commission of Radiological Protection (ICRP), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), UK National Radiological Protection Board’s Advisory Group on Ionizing Radiation and also formerly a member of the Executive Committee of the International Association of Cancer Registries.

Research Interests

• Cancer risks associated with exposure to ionizing radiation and how the radiation-related risks are modified by modes of exposure and other factors including age, gender, time as well as other host and carcinogenic factors.
• The risk and dose-response for chronic diseases other than cancer associated with exposure to ionizing radiation.
