We are investigating the dynamics of polycyclic aromatic hydrocarbons in the Seto Inland Sea and other areas of western Japan. In addition, clarifying the mechanism of contamination of Lake Kojima, we are conducting water quality surveys of Lake Kojima and elution experiments of organic matter and nutrient salts from the bottom sediment. We are also investigating the effects of chemical substances on the properties of aquatic organisms.

Physarum polycephalum can servive in extreme desiccation conditions. Stabilization of biomolecules, including proteins, is essential action for survival in the desiccation condition. To understand the molecular mechanism of desiccation tolerance in Physarum polycephalum, I have researched the whole aspect of adaptation by omics analysis.

My research focuses on elucidating the structure and function of biopolymers involved in the human life sciences. In particular, I focus on the field of human taste perception and study the mechanism of sweet taste perception. I also studies proteins that transform the human sense of taste. Certain proteins have the ability to alter human taste perception (e.g., changing sour taste to sweet). I believe that by elucidating this mechanism, we may be able to change “undesirable tastes” into “desirable tastes.
