Ichiro Maruyama is a Professor at the Okinawa Institute of Science and Technology Graduate University (OIST). He received his Ph.D. from University of Tokyo, Japan. Subsequently he was trained as a post-doctoral fellow in MRC Laboratory of Molecular Biology, Cambridge, UK, where he started to work on neurobiology of the nematode Caenorhabditis elegans. Ichiro then moved to The Scripps Research Institute, La Jolla, California, USA, where he started to study molecular mechanisms underlying activation of cell-surface receptors. At OIST, Ichiro continues to work on learning, memory and decision-making in C. elegans as well as on molecular mechanisms of transmembrane signaling mediated by cell-surface receptors.
