Other Activities Professor at Tohoku University Visiting scientist at National Institute of Advanced Industrial Science and Technology (AIST) Chairman of IODP committee, Japan Drilling Earth Science Consortium Future Plan Research will be extended to time-integrated global environmental change. Messages to Students I hope that you will have many interests in topics dealing with natural environments and be able to think by yourself. You gain a new understanding of global/regional/local environmental systems in both modern times and in the past.
