Curriculum Vitae
Professor Kaoru Yamanouchi has been Professor of Chemistry at the University of Tokyo since April 1997. His research fields are in physical chemistry; especially, gas phase laser spectroscopy, chemical reaction dynamics, and intense laser science.

Honors: He has been the recipient of Morino Fellowship endowed by Morino Foundation (1987), Spectroscopical Society of Japan Award for High-Quality Papers (1989), Chemical Society of Japan Award for Young Scientists (1991),Japan IBM Prize (2000), Fellow of Institute of Physics (2004), The Best Paper Award of the Laser Society of Japan (2008), The 67th Chemical Society of Japan (CSJ) Award (2015), The 7th Japan Society for Molecular Science Award (2016), The Japanese Photochemistry Association Lectureship Award (2017), and Medal of Honor with Purple Ribbon (2020).

Biographical & Education: He was born on April 27 (1957) in Tokyo, Japan, and graduated from Department of Chemistry, the University of Tokyo in 1981. After receiving Master's Degree from Graduate School of Chemistry in 1983, he received Doctor's Degree from the same graduate school in 1986 with the thesis title of "Structural Chemical Studies on Rotational Isomerism, Nuclear Quadrupole Coupling, and van der Waals Interaction."

Experience: One year before receiving the doctor's degree he was appointed as Research Associate at Department of Pure and Applied Sciences of the University of Tokyo. He was promoted to Associate Professor in 1990, and had been in the position for seven years until he became Professor of Chemistry in 1997.

Association: He is now Associate Member of Science Council of Japan, Member of Chemical Society of Japan and American Physical Society, and Executive Committee Member of Japan Intense Light Field Science Society. He is also International Advisory Committee Member of Journal of Physics B: Atomic, Molecular and Optical Physics, Series Editor of Springer's Series in Chemical Physics, Series Editor of Springer's Series in Topics in Applied Physics, Chief Editor of Springer's Sub-series, "Progress in Ultrafast Intense Laser Science" and Editorial Board member of Chemical Physics (Elsevier).

Research Activities: For more than twenty years, Professor Kaoru Yamanouchi has pioneered the field of Molecular Science. Until 10 years ago, his major research area was that related with intramolecular dynamics of highly excited molecules and clusters. On the basis of the development of laser spectroscopic techniques, he elucidated how the information of ultrafast nuclear dynamics is encoded in high resolution frequency domain spectra. For example, by combination of dispersed fluorescence and stimulated emission pumping spectra of SO2 and acetylene, he was able to elucidate the existence of the stepwise vibrational energy redistribution process. Furthermore, on the basis of the development of tunable vacuum ultraviolet light sources, he elucidated ultrafast dissociation process of OCS on the mostly repulsive potential energy surface in the VUV region. The series of his studies has been known as that demonstrated clearly ultrafast dynamics of molecules in the time domain can be extracted from spectra in the frequency domain.

In 1996, he launched a new research project to investigate how atoms, molecules, and clusters behave in an intense laser field whose magnitude is as large as that of a Coulomb field within atoms and molecules. By developing new experimental techniques such as mass-resolved momentum imaging, pulsed gas electron diffraction, and coincidence momentum imaging, Professor Yamanouchi showed that molecules undergo ultrafast skeletal deformation in ultrashort pulsed intense laser fields. Through the collaboration with Professor F. Kannari at Keio University, Professor Yamanouchi demonstrated that the selective bond breaking of ethanol is realized in a short pulsed intense laser field by systematically changing the temporal duration of the intense laser fields.

Besides the experimental pursuit, Professor Yamanouchi developed a new theoretical approach called the algebraic force field expansion for treating highly excited vibration of polyatomic molecules. He also developed a quasi-stationary Floquet approach to treat dissociative ionization of H2+ in intense laser fields and demonstrated theoretically the signatures of dressed photon states appear in a kinetic energy spectrum of H+.

Science Promotion: Professor Yamanouchi is one of the world-leading scientists in the new interdisciplinary field called ultrafast intense laser science. From FY2002 he has been Head of Priority Area Program on Control of Molecule in Intense Laser Fields supported by MEXT, Japan, and Head Coordinator of Core-to-Core Program on Ultrafast Intense Laser Science supported by JSPS, Japan. In the former program, a total of 42 domestic research groups are involved, and interdisciplinary interactions have initiated as many as 20 joint projects among the member research groups. In the latter program, international efforts to promote the research area of ultrafast intense laser science have been made through the cooperation with 56 research groups in the six developed countries, that is, Canada, France, Germany, Italy, UK, and US. Professor Yamanouchi has organized a series of international symposia in these years as a chairman or as one of the cochairmen. For example, "International Symposium on Ultrafast Insense Laser Science (ISUILS)" that was started in 2002 has now received world-wide recognition as the most successful symposia in this new research fields. Professor Yamanouchi also organized Asian Symposium on Intense Laser Science 1 in 2004 at Tokyo, and The 1st Shanghai-Tokyo Advanced Research (STAR) Symposium on Ultrafast Intense Laser Science at Tokyo in 2009 (organized every year alternating hosts between Shanghai and Tokyo groups) to promote the research field in Asian countries.

Publications: Professor Yamanouchi is the author of 259 original papers (as of 2020).
