Complex nonlinear phenomena such as rhythms, patterns, and chaos are found in the natural environment and the living system. For these models, we are studying nonlinear dynamics in the chemical system, which include the occurrence of oscillations, the pattern formation, the chaos phenomena, and their control by light. We believe that determining the temporal and spatial organizations in the nonlinear chemical system maintained far from equilibrium is important when we intend to understand the diversity, the complexity, and the functionality along with self-organization in the environmental system or the biological system. We also advance our research on the contamination of environment by chemical substances and their effects on the biological systems from the view point of system dynamics.

Subject of research

• Nonlinear dynamics in the chemical system and their photoresponses
• System dynamical approach to the issue of environmental pollution by chemical substances
