I've been engaged in the academic field of polar-sea physical oceanography. Basically, I love visiting beautiful places, i.e. the fields in the Arctic or anywhere else on the earth. Particular insterests are ice and oceanographic dynamics, and their coupling system. My works to date are concerned with sea-ice modeling, internal gravitiy waves, mesoscalar vortices, turbulence in the ocean, etc.
