Biography

Tatsuhiko Imaoka completed his PhD at the University of Tokyo Graduate School of Science (zoology and biological sciences) in 2002. In 2000 and 2001, he studied mammary gland biology as a Visiting Scientist of Prof. Nelson Horseman’s Laboratory at the University of Cincinnati College of Medicine, USA, and clarified the autocrine role of serotonin in regulating the lactational activity in the mammary gland, which became a part of his doctoral thesis. In 2002, he became a researcher at the National Institute of Radiological Sciences (NIRS), Japan, and started to engage in the animal radiobiology projects led by Dr. Yoshiya Shimada. In 2016, the NIRS was reorganized as the National Institutes for Quantum Science and Technology (QST), and he became a Group Leader at the Department of Radiation Effects Research, Institute for Radiological Science in QST. Since July 2024, he has been the Director at the Department of Radiation Effects Research. He is also involved in the quantum life science project at QST and a member of the PLANET Steering Committee, a Visiting Professor at the Tokyo Metropolitan University, a Vice President of the Japanese Radiation Research Society, and a corresponding member of the International Commission on Radiological Protection Task Group 111. He specializes in radiobiology, with his interests covering radiation carcinogenesis, stem cell biology, integration of radiation epidemiology and biology, and biomedical application of quantum technology.
