My original area of specialty is planet formation theory, which may seem quite distant from Environmental Studies. However, planetary science themes such as how planet earth came to be formed, and how its surface environment has been maintained, are in fact related to the very heart of Environmental Studies. My research themes that are directly connected to Environmental Studies include the use of simple models to investigate climate systems and the coevolution of life and the earth. I am the Education Promotion Chief of this GCOE program, and have set the educational curriculum for the Integrated Environmental Studies Course in collaboration with other members of staff. I have given particular attention to establishing appropriate research themes for the Class and Research Instruction in Basic Environmental Studies, and constructing a platform for joint research. I am hoping that this GCOE program will help to promote the development of new and innovative research and education.

Research Themes

  1. Planetary Formation Theory: Recently, extrasolar planetary systems have been discovered, in addition to the Solar System. Using information from these planetary systems, I have developed a comparative theory of planetary system formation, and examine the factors contributing to the establishment of the earth environment.
  2. Simple Modeling of Climate Systems: The construction of models linking the material and energy cycles of the earth's surface. In particular, I am interested in research on climate fluctuations caused by the coupling of ocean carbon cycles with thermohaline circulation. I am also a strong advocate of the Dynamics of Sun-Earth-Life Interactive System (SELIS) .
  3. Coevoluation of life and earth: Analysis of feedback mechanisms through land vegetation, the relationship between the evolution of plant photosynthesis and climate change, the expansion of dynamic vegetation models.
