Profile

Osamu ICHIKAWA is a professor of Faculty of Data Science at Shiga University. He received B.E. and M.E. degrees in Aeronautical Engineering from Tokyo University, Japan, in 1986 and 1988, respectively, and a Ph.D. degree in Information Science from Nara Institute of Science and Technology, Japan, in 2008.
He joined IBM Japan, Yamato Laboratory in 1988. He worked on software development including operating systems, voice software, multimedia, system management and satellite broadcasting data delivery. From April 1999 to March 2001, he was a funded researcher at the Institute of Space and Astronautical Science in Sagamihara, Japan, for research on computational fluid dynamics. In 2001, he joined the IBM Tokyo Research Laboratory, Japan, working on signal processing for automatic speech recognition. In 2018, he moved to Faculty of Data Science of Shiga University.
His research interests include auditory speech processing, robust speech recognition, microphone arrays, acoustic echo cancellation, and neural network modeling.
Dr. Ichikawa is a senior member of IEEE and the Institute of Electronics, Information and Communication Engineers (IEICE). He is also a member of the Acoustical Society of Japan.
