Masataka Taga


Department of Molecular Biosciences


Dr. Taga received his degree for research on radiation sensitivity in early mouse embryos. Since assuming his position at the Radiation Effects Research Foundation, he has been involved in research on radiation carcinogenesis and investigated molecular alterations in radiation-associated thyroid and lung cancers. Currently, he is analyzing the molecular mechanisms of radiation liver carcinogenesis using a mouse model system.
