About

Dr. Tomonori Hayashi has been studying the immunology of A-bomb survivors in the Immunology Laboratory of the Department of Radiobiology (now the Department of Molecular Biosciences) at RERF since 1990. He was a research fellow at Michigan State University (MSU), USA, from 1993 to 1995, where he studied cell-cell communication and mechanisms of human breast cancer development. He returned to Japan in 1995 and has been studying the effects of radiation exposure on the immune system of atomic bomb survivors and the genetic background of the relationship between radiation exposure and the development of radiation-related cancer and non-cancer diseases. His current interests include clarifying the effects of radiation exposure on immunological aging and whether differences in the genetic backgrounds of A-bomb survivors influenced the development of radiation-related diseases by comprehensive genome studies.
