Mitsuyoshi Urashima

Dr. Mitsuyoshi Urashima
Dr. Urashima's traces his motivation to become a pediatrician to a documentary he watched in primary school about the explosion of the atomic bombs over Hiroshima and Nagasaki, and the subsequent rise in leukemia among the children who survived. After graduating from the Jikei University School of Medicine in 1986 and training as a pediatric oncologist in Tokyo, he studied at the Dana-Farber Cancer Institute (Boston). He realized, however, that neither molecular biology nor conventional pediatric methods could save large numbers of people, so he turned his attention to epidemiology, studying at the Harvard School of Public Health (MPH in 2000). He currently administers an outpatient clinic at the Jikei University hospital, where he spends the majority of his time on research. He has also written more than 120 original articles and recently launched an initiative aimed at educating the next generation to help save peoples' lives.
