Dr. Fumio Okada received BE from the University of Tokyo in 1978, MS from the University of California at Irvine in 1989, and Dr. Eng. from the University of Tokyo in 1994. He entered Nippon Mining Co. Ltd in 1978 and worked as an engineer and as a researcher until 2002. After retiring the company, he became a Prof. in the Department of Chemical System Engineering, the University of Tokyo. He moved to the Department of Environmental Chemistry, Kogakuin University in 2012. There he teaches Reaction Engineering, Heat Transfer Engineering, and Physical Chemistry for undergraduate students and Environmental System Engineering for graduate students. His research is now focused on the electrochemical production of functional water, such as ozone dissolved water, hydrogen dissolved water, and advanced oxidation water which comprises of ozone and hydrogen peroxide dissolved in water. He also developed a highly efficient gas-liquid mixer which enables the production of ozone dissolved water without ozone gas emission. In that process, all of the ozone gas formed in water electrolysis is dissolved into water by passing it in the mixer. He was an amateur boxer when he was a student in the University of Tokyo, won the Championship of Tokyo in the lightweight, and became a candidate for the Olympic Games in Moscow. His record was 17 wins (14 KO) and 4 losses. His nickname was the “Rocky of the Red Gate (The Red Gate is the symbol of the University of Tokyo)”. He still coaches boxing to the students in Kogakuin University.
