He completed his undergraduate and graduate studies at Osaka University under the direction of Prof. Hisashi Matsuda in 1987. He was a fellow of the Japan Society for the Promotion of Science for Japanese Junior Scientists from 1986 to 1987. He received his Ph.D. in 1987 from Osaka University. He was a research associate of Osaka University from 1987 to 1996. He received the Research Award from the Mass Spectrometry Society of Japan in 1997.
Cluster is a micro laboratory of surface science and an example of small body systems.
The study of cluster is located in between molecular physics and material science. Clusters are expected as a new material having new specific characters for 21st century. In order to investigate the characteristics of clusters, we measured the stability of cluster ions according as their sizes and the life times of metastable cluster ions. We have developing a new cluster ion source, which can be generated complex clusters made of metal atoms and organic molecules. We have also studying the mechanism of the cluster formation.
