Tomoko M. Nakanishi In 1978, She got Ph.D. in radiochemistry from The Univ. of Tokyo. She is now an Emeritus Prof. of The Univ. of Tokyo and former President of Hoshi Univ. She has been enthusiastic about the development and application of imaging techniques using radiation and radionuclides in plants. Her research strategy excels by optimizing various complementary radiochemical/nuclear analytical techniques and innovative experimental set-ups to get insight into a part of plant physiology. Her work was published by Springer as an open access book, entitled "Novel Plant Imaging and Analysis -Water, Elements and Gas Utilizing Radiation and Radioisotopes. (Nakanishi, T.M., 2021) She received Hevesy Medal Award, an Honorary Doctor of Chalmers University of Technology in Sweden, an Ordre National du Mérite from the French government, etc. She is a board member of the Fukushima Institute for Research, Education, and Innovation to manage the reconstruction and development ofthe suffered area in Fukushima.

Keitaro Tanoi Prof. K. Tanoi got Ph.D. in Agriculture, The University of Tokyo in 2011. He became a Prof. at the Graduate School of Agricultural and Life Sciences at The University of Tokyo in 2018. His interest is in applying radiation and radioisotope to agriculture studies or bioscience. He is now involved in studies of mineral transport in plants using radioisotopes as tracers. Periodically, he is producing unique radioisotopes with short half-lives, such as Mg-28, utilizing an accelerator for the tracer work. He is a manager for all the researchers and facilities utilizing radioisotopes in the faculty. He is an expert in radioisotope measurement and analysis. Since 2011, right after the nuclear accident in Fukushima, he has studied radioactive cesium dynamics in agricultural fields, along with experiments in the lab.
