Yoshifumi Nishio received the 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 are in the areas of nonlinear circuits engineering, including 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, neural network architecture, complex networks, evolutionary computation, and bio-signal processing.

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 the Chair of the IEEE CAS Society Shikoku Chapter during 2011-2014, and is currently a member of the IEEE CAS Society Board of Governors (from 2012).
He was an Editor of the IEICE Fundamentals Review during 2007--2012 and an Associate Editor of the IEEE Transactions on Circuits and Systems--I: Regular Papers during 2004--2005, the IEEE Transactions on Circuits and Systems--II: Express Briefs during 2012--2013, the IEEE CAS Magazine during 2008--2009, and the RISP Journal of Signal Processing during 2005--2012. He is currently serving as a Secretary for the NOLTA, IEICE (from 2009) and an Associate Editor for the IEEE CAS Society Newsletter (from 2007) and International Journal of Bifurcation and Chaos (from 2015). He is also 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.
