      Profile in English

      Prof. Satoshi Taguchi is Professor of Space Physics. His current research interests are (1) the dynamical coupling between the solar wind and dayside magnetosphere, (2) the global characteristics of the ionospheric convection system, and (3) the mesoscale interaction of the ionosphere and neutral atmosphere. He was born in Kyoto, and educated in space physics at Department of Geophysics, Kyoto University. After obtaining his phD in 1992, he worked at University of Electro-Communications (in Tokyo), and at NASA/GSFC (in Maryland, US). In April 2014 he moved to Kyoto University from UEC.
