Dr. Naoyuki Tokuda graduated from Yokohama National University in 1959 with B.S degree in Mechanical Engineering. He won a Fulbright Scholarship in 1961 obtaining a M.S degree from Stanford University, California in 1962 and a Ph.D degree from University of Michigan, Ann Arbor, Michigan in 1966 both in Mechanical Engineering.

From 1966 to 1968, he has been a research scientist at Lockheed Research Center at Marrietta, Gerogia working on aerodynamics and fluid mechanics fields. During 1969 and 1971 academic year, he was a visiting scholar at the Department of Applied Mathematics and Theoretical Physics, University of Cambridge and also a senior scientist at Mathematics Department of Southampton University in England from 1971 to 1972 where he has done extensive research work in the field of fluid mechanics and applied mathematics.

From 1973 on, he has been a Professor of Computer Science and a Director of Information Processing Center of Utsunomiya University, Japan, until he retired from teaching in April of 2001. Since April of 2001 on, he has been a Director of R&D Center of SunFlare Company in Tokyo, Japan.

His current interest in research includes the area of natural language applications focusing on advanced technology of combined DLSI (differential latent semantics Indexing)-based content and syntactics-based information retrieval by template matching including EDT-FAQ-SEEKER as well as ATN-based template and DLSI-based computer-assisted machine translation between two languages, and image recognition technology based on stability analysis of regional voting against noise in decision making, and other wide varying subjects.
