Biography:
Dr. Ishida joined the research group of Prof. Teijiro Yonezawa at the Kyoto University in 1970. He received his PhD degree in 1975 at the same university. After one year postdoctoral fellowship supervised by Prof. Keiji Morokuma at the Rochester University, New York, he obtained the position of a lecturer at the Science University of Tokyo. He was retired from the university in 2011. He has published more than 30 articles in science journals. For example, most important three articles are listed below:
[1] K. Ishida, “Core radial polarization and the contact hyperfine structure of 4S state of nitrogen”, Phys Rev A12 (1975) 1153-1158.
[2] K. Ishida, “Calculus of several harmonic functions”, J Comput Chem Jpn. Int. Ed. 8 (2022) 2021-0029.
