I Joined JAGFOS meeting in Bad Neuenahr organized by Japan Society for Promotion of Science, Alexander von Humboldt Foundation, and U. S. National Academy of Science. The symposium is designed so that “young” researchers from three countries and various academic fields can enjoy interdisciplinary exchange and discussion to extend their knowledge and human network. I enjoyed this meeting a lot! The picture is the one taken with Dr. Takeda and Prof. Iye.
