Kotaro Kohno is a professor and director at the Institute of Astronomy, Graduate School of Science, the University of Tokyo. He received his PhD in 1998 for observational studies of dense molecular gas in Seyfert and starburst galaxies using Nobeyama Millimeter Array. His research focuses on spatially resolved studies of galaxies using ALMA and JWST, and on surveys at submm/mm/radio wavelengths using techniques such as gravitational lensing, radio-optical crossmatching, and line intensity mapping. He is also actively involved in instrumentation development for these studies.
