Hiroyuki Enomoto is director of Arctic Environment Research Center (AERC) of National Institute of Polar Research (NIPR) in Japan, and professor of the Graduate University for Advanced Studies. Since 2014, he is vice director-general of NIPR. He received PhD at the ETH Zurich in 1989, on physical geography on sea ice and climate relationships. His research area is climatological investigations of snow and ice of ocean, land and ice sheet in the Arctic, Antarctic and snow cover area in the middle latitudes. Using satellite microwave remote sensing and visiting polar snow and ice field, he is widely scanning changing cryosphere. His first visit to glacier was Patagonia in 1981.Since then, he has worked at many cold regions. He is visited Svalbard by opening Japanese Arctic research station, and also Dome Fuji Antarctica for starting up new Antarctic inland station and drilling site and AWS monitoring. He joined Japanese, Australian and Swedish Antarctic Expeditions, and in the Arctic, he worked often in the Alaska as the collaborator of IARC/UAF and Japanese project on linkage of land-sea ice processes. Since 2011, he is working as the leading member of the Japanese Arctic research project, and also working with international cryospheric and Arctic meetings. He is happy to seek for scientific frontier of cryosphere, and also collaborations in international polar expeditions and in community works as well.
