He has been dedicated to membrane science and technology for more than 40 years. His research experience started with nanofiltration in terms of membrane preparation and the transport mechanism of electrolytes through charged porous membranes. Upon joining Hiroshima University, his interests have expanded to inorganic and organic/inorganic hybrid membranes, involving the preparation of subnano-nanoporous Si-based membranes, characterization, transport mechanism, and the applications to gas and liquid phase separation. He has authored and co-authored over 300 SCI papers and 50 book chapters. He served as the President of The Membrane Society of Japan in 2013 and 2014, and is also an editorial board member in Journal of Membrane Science. He is selected as Distinguished Professor at Hiroshima University
