Welcome to the BioGeochemistry Reseach Group

About Us

We are studying biogeochemical cycles on Earth to clarify past, present, and future state of our environment, using the distributions of natural stable isotopes as tracers. In particular, we are interested in the sources and fates of trace gas components on Earth surface, using the stable isotopes of carbon, oxygen, hydrogen, and nitrogen. Development of related sampling/analytical techniques are also included in our interests.

Major fields of our research:

  • Biogeochemcial processes
  • Atmospheric and oeanic trace gases
  • Sea floor gas hydrates
  • Microbial activities under extreme environments
  • Mass spectrometry
