Tomoko Imasaka was born in 1964 in Fukuoka City, Japan. She completed the bachelor course at Kyushu University on March, 1987 and entered the graduate school. She was employed as a laboratory assistant by the Kyushu Institute of Design on May, 1987. The institute was brought together with Kyushu University, and she received the doctoral degree of engineering from Kyushu University in 2004. She was promoted to a lecturer in 2017. During her carrier, she studied the quantum effects on the orientational ordering of the guest molecules enclosed in –hydroquinone clathrate. She investigated and found that both quadrupole moments and polarizabilities of polychlorinated dibenzofurans change systematically with the chlorination pattern governing molecular charge distribution by using density functional theory. In addition, she theoretically predicted the transition energy and the ionization energy of the explosive substances including triacetone triperoxide and the toxic substances such as dioxins by means of quantum chemistry. She also invented a method for analyzing the spectral data obtained using gas chromatography/time-of-flight mass spectrometry and developed a program for calculating a reliability factor and improved the detection limit using a software written by a Fortran language. More recently, she proposed a new method for measuring the pulse width approaching 1 fs, a theoretical limit for an optical wave. This approach is based on the measurement of an autocorrelation trace using a mass spectrometer as a two-photon-response detector. Based on the quantum chemical calculation, she found a series of organic molecules suitable for non-resonant two-photon ionization in a wide spectral range that is essential for the measurement of an ultrashort optical pulse. She has reported more than 42 original papers in the journals published by the American Chemical Society (Anal. Chem. (2010, 2015, 2016, 2018), Chem. Res. Toxicol. (2005), J. Phys. Chem. A (2001)), the Royal Society of Chemistry (Analyst (2009, 2017)), Elsevier (Opt. Commun.(2012, 2013), Anal. Chim. Acta (2011, 2014, 2017)), Springer (Applied Physics B (2013)), etc. Her publications have been cited 271 times to date in academic journals. She also made 42 presentations in the international conferences that include Euroanalysis, Asianalysis, and the Winter Colloquium on the Physics of Quantum Electronics. At 4th Asia Oceania Mass Spectrometry Conference and 10th Taiwan Society for Mass Spectrometry Annual Conference, she made a keynote presentation. She also presided over the international symposium which both presidents of National Taiwan Normal University and Kyushu University attended in 2018. She is a member of the American Chemical Society, the Optical Society (OSA), the Japan Society of Applied Physics, the Chemical Society of Japan, and the Japan Society for Analytical Chemistry. She has received several research funds supplied from the Japan Society for Promotion Science and also from the industrial societies for solving the environmental issues.
Prof. Totaro Imasaka, born in 1950, studied chemistry at Kyushu University. He received the doctor degree in the field of applied chemistry in 1978. After receiving the doctoral degree, he was a postdoctoral fellow at Stanford University. Since 1979 he was an employee of Kyushu University. He was appointed to assistant processor, lecturer, associate professor, and full professor, in 1979, 1980, 1981, and 1991, respectively. He was promoted to distinguished professor and specially-appointed professor in 2009 and 2016, respectively. Professor Imasaka is author or co-author of more than 326 peer-reviewed publications, 143 review/article/books, and 47 patents. He received The Chemical Society of Japan Award for Young Chemists in 1984 for the title, "Study on Laser-Induced Spectrometry for Ultratrace Analysis". He also received The Divisional Award of The Chemical Society of Japan in 1994 for the title, "Studies on Two-Color Stimulated Raman Effect". More recently, he received The Award of The Japan Society for Analytical Chemistry in 2002 for the title, “Development and Application of Supersonic Jet Spectrometry and Near-Infrared Laser Spectrometry”. He was a member of the editorial advisory board for the international journals: Chemometrics and Intelligent Laboratory Systems, Analytical Methods and Instrumentations, Fresenius' Journal of Analytical Chemistry, Talanta, Analytical Chimica Acta, and Analytical Chemistry. He was serving as an editor of Analytical Sciences, the international journal published by the Japan Society for Analytical Chemistry and is serving as a section editor of Optics and Lasers in the journal of Applied Sciences published by Multidisciplinary Digital Publishing Institute (MDPI). He was as a titular member of the International Union of Pure and Applied Chemistry (IUPAC) and is honored to serve as a fellow of this society
