Curriculum

Yoshifumi Nishio received B.E., M.E., and Ph.D. degrees in electrical engineering from Keio University, Yokohama Japan, in 1988, 1990, and 1993, respectively.

In 1993, he joined the Department of Electrical and Electronic Engineering at Tokushima University, Tokushima Japan, where he is currently a Professor. From May 2000 he spent a year in the Laboratory of Nonlinear Systems (LANOS) at the Swiss Federal Institute of Technology Lausanne (EPFL) as a Visiting Professor.

His research interests include analysis and application of chaos in electrical circuits, analysis of synchronization in coupled oscillatory circuits, development of analyzing methods for nonlinear circuits, theory and application of cellular neural networks, and neural network architecture.

He was the Chair of the IEEE CAS Society Technical Committee on Nonlinear Circuits and Systems (NCAS) during 2004--2005, the Steering Committee Secretary of the IEICE Research Society of Nonlinear Theory and its Applications (NOLTA) during 2004--2007, and is currently the Secretary/Treasurer of the IEEE CAS Society Shikoku Chapter.
He was an Associate Editor of the IEEE Transactions on Circuits and Systems--I: Regular Papers during 2004--2005 and the IEEE CAS Magazine during 2008--2009, and is currently serving as an Associate Editor for the IEEE CAS Society Newsletter and the RISP Journal of Signal Processing.
He is also the Editor of the NOLTA, IEICE and the IEICE Fundamentals Review and is a member of the Editorial Board of International Journal of Circuit Theory and Applications.
He is a senior member of the IEEE, and a member of the IEICE and the RISP.
