Yoshihiko Hatano, director general, Advanced Science Research Center, Japan Atomic Energy
Agency (JAEA), Tokai, and professor emeritus, Tokyo Institute of Technology, Japan, received his
PhD in chemistry from Tokyo Institute of Technology in 1968. Since then he has worked in different
capacities in the Department of Chemistry at Tokyo Institute of Technology, as follows: associate
professor, 1970–1984; professor, 1984–2000; and dean of the Faculty of Science, 1997–1999. After
retiring from Tokyo Institute of Technology in 2000, he worked as a professor in the Department
of Molecular and Material Sciences at Kyushu University, Kasuga, Japan, from 2000 to 2003 and
as distinguished professor at the Synchrotron Radiation Research Center at Saga University, Saga,
Japan, from 2004 to 2009. Since 2005, he has served as the director general of the Advanced
Science
Research Center, JAEA until his retirement from it at the end of March 2010.
Dr.
Hatano has been a visiting scientist/professor at many institutions, including the University
of Notre Dame, Indiana; the University of Kaiserslautern, Germany; the University of California,
Berkeley; the University of Science and Technology of China, Hefei; International Atomic
Energy Agency (IAEA); and High Energy Accelerator Research Organization (KEK) at Photon
Factory. He has also served in other scientic capacities: chairperson of the Japanese Society of
Radiation Chemistry and the Society for Atomic Collision Research; advisory editor of Chemical
Physics Letters; coeditor of Charged Particle and Photon Interactions with Matter: Chemical,
Physicochemical, and Biological Consequences with Applications,MarcelDekker, New York(2004);
councilor of the International Association for Radiation Research, the Chemical Society of Japan,
and the Japanese Society of Synchrotron Radiation Research; and chair/cochair of the International
Symposium on Chemical Applications of Synchrotron Radiation, the International Symposium on
Electron-Molecule Collisions and Swarms, the International Conference on Photonic, Electronic,
and Atomic Collisions; and the International Symposium on Advanced Science Research.
His research interests include (1) primary and fundamental processes in charged particle and
photon interactions with matter, (2) spectroscopy and dynamics of molecular superexcited states in
the dissociative excitation of molecules in photonic or electronic collisions with molecules, (3)electron
attachment and recombination, and (4) collisional de-excitation of excited rare gas atoms. He is the
author or coauthor of more than 280 refereed journal articles, scientic papers, and books.
Yosuke Katsumura, professor, received his PhD from the Department of Nuclear Engineering
and Management, School of Engineering, the University of Tokyo, Tokyo, in 1981. He is also a
group leader of Basic Radiation Research, Advanced Science Research Center, Japan Atomic
Energy Agency. He has previously worked as a research associate, Nuclear Engineering Research
Laboratory, 1972–1984; as an associate professor, Department of Nuclear Engineering, 1984–
1994; as a professor, Department of Quantum Engineering and Systems Sciences, 1994–1996;
Nuclear Engineering Research Laboratory, 1996–2004; Department of Nuclear Engineering and
Management,
the University of Tokyo, 2005–present.
Dr.
Katsumura has been a visiting professor/fellow at many universities and institutions worldwide,
including the Swiss Federal Institute of Technology (ETH, Zürich), Switzerland; the University of
Science and Technology of China; the University of Sherbrooke, Canada; and the University of Paris-
Sud, Orsay, France. He was the president of the Japan Society of Radiation Chemistry in 2007 and 2008,
and is the division head of the Water Chemistry Division, Atomic Energy Society of Japan, since 2009.
He received an award from the Japan Society of Radiation Chemistry in 2005. He has published more
than 220 articles in peer-reviewed journals and books. He has also organized several international
symposia of radiation chemistry and edited special issues of Radiation Physics and Chemistry.
