Profile
Shizuo Tokito received Doctor of Engineering and Master of Engineering degrees from Graduate School of Engineering and Sciences, Kyushu University, and become an Assistant Professor of Kyushu University. He also worked as a postdoctoral researcher under Prof. Alan J. Heeger, Nobel Prize laureate in chemistry, at UC Santa Barbara (US). After that, he joined Toyota Central R&D Labs Inc. as Senior Research Engineer and later then Science & Technology Research Laboratories of Japan Broadcasting Corporation (NHK) as a Research Director. Currently he is a Director and Distinguished Research Professor at the Research Center for Organic Electronics (ROEL) within Yamagata University. He maintains a large research group of more 50 people including visiting researchers from many partner companies in industry. He also published more 250 papers in the areas of organic light emitting diodes and organic thin film transistors (TFT), printed TFT circuits, biosensors as well as related flexible and printed electronics.
