Personal and Team Information

Yoshiyuki Kageyama was born in Hiroshima in 1977 and obtained his Ph.D. from the University of Tokyo in 2006 under the direction of Prof. Shigeru Murata. He continued his study of the construction of biomimetic supramolecular systems based on organic chemistry as a postdoc in Prof. Tadashi Sugawara's group at the University of Tokyo. Next he moved to the Faculty of Pharmaceutical Science at Tokyo University of Science as a postdoc and studied organic photochemistry and molecular-recognition chemistry in aqueous media under the direction of Prof. Shin Aoki. In 2009, he became an assistant professor at Laboratory for Condensed Matter Chemistry at Hokkaido University. His specialty is physical organic chemistry, especially the kinetic study of organic reactions.

    He is interested in the construction of integrated chemical systems that work cooperatively with their dynamic properties. When considering life phenomena, we can recognize the importance of supramolecular dynamics in their highly functionalized homeostatic feature. A well-known example is the allosteric effect of hemoglobin: the change in its structure realizes the self-catalytic trapping and releasing of oxygen. Heartbeat is another example, in which the cells, which consist of molecules, work cooperatively to beat periodically and enduringly.

    To create excellent chemical systems toward biological systems, he creates and analyzes functional and dynamic soft molecular assemblies in water. His significant studies are listed below.
