Shuji Tsuruoka obtained a Ph.D. in Chemical Engineering from the University of Arizona in 1986. He subsequently worked for Unilever and SC Johnson before joining Mitsui (Tokyo) in 2002 where he worked on the development of nanotechnology. He has been a professor at Shinshu University in Japan since 2011.
Dr. Tsuruoka has made significant contributions to the emerging field of nanotechnology and nanotoxicological evaluations. He collaborates with major tox study institutes over the world by supplying Mitsui MWNT-7 MWCNTs that is the benchmark of nanotox evaluation and listed in the WHO-IARC monograph at present. Meanwhile, he collaboratively explores Redox potential of CNTs in terms of biological activities, i.e., ROS reactions in aqueous solutions. Furthermore, he acts as a regional government advisor to small manufacturers keen to develop new technologies with nano carbons. This activity has given rise to innovative industrialized products including CNT yarn and sensors, Carbon Fiber Glued Press, transparent CNT ink.
