Ph.D. Yoshiyuki Kageyama

A pioneering researcher in Systems Chemistry for autonomous behavior in multi-molecular systems. The interdisciplinary field of chemistry and physics can be contributes the development in micro-robotics and comprehension of origin-of-life.

    Yoshiyuki Kageyama is working as 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.
