Dr. Jeffries is currently on leave from UAF and working at the Office of Naval Research, where he is a Program Officer and Arctic Science Advisor in the Ocean, Atmosphere and Space Research Division, Ocean Battlespace Sensing Department. Prior to going to ONR, Dr. Jeffries spent four years (2006-2010) at NSF, where he was the Program Director for the Arctic Observing Network in the Division of Arctic Sciences, Office of Polar Programs. His cryospheric processes research has taken him to both the Arctic and the Antarctic to investigate ice shelves, icebergs, sea ice and lake ice. With Kim Morris, Dr. Jeffries created the very successful Alaska Lake Ice and Snow Observatory Network (ALISON), an integrated research and education project in which K-12 teachers and students were his scientific partners in an investigation of lake ice growth, snow accumulation and conductive heat flux in Alaska.
