Makusu Tsutsui is an Associate Professor at the Institute of Scientific and Industrial Research (SANKEN) at Osaka University in the Department of Bio-Nanotechnology. He received his Ph.D. in applied physics and engineering from Kyoto University in 2006. He subsequently joined Osaka University and has developed research programs centered on solid-state nanopores, iontronic devices, and electrochemical control of ionic transport at the nanoscale.
His work integrates nanofabrication, electrochemistry, and biomolecular engineering to elucidate and control ion transport and molecular interactions in confined systems. His current research is directed toward the development of next-generation sensing and computing technologies that exploit ions as functional carriers, including projects on fifth-generation sequencing technologies for DNA, RNA, and proteins aimed at cancer diagnostics and drug discovery.
