Matthew Druckenmiller (SIAN Engagement and Communications Lead) earned his PhD from the University of Alaska Fairbanks where he combined geophysical monitoring with local knowledge to study how Iñupiat communities use and rely on a changing sea-ice environment. Previously, Matthew was a PACE (Postdocs Applying Climate Expertise) Fellow at the National Snow and Ice Data Center (NSIDC) where he collaborated with Alaska’s North Slope Borough to investigate the impacts of Arctic sea ice loss on bowhead whales. With long-held interests in science policy, he has served as a Science Policy Fellow at the National Academies’ Polar Research Board and a AAAS Science Policy Fellow at the U.S. Agency for International Development.

Jennifer Francis (SIAN Co-lead) earned a B.S. in Meteorology from San Jose State University in 1988 and a PhD in Atmospheric Sciences from the University of Washington in 1994. As a professor at Rutgers University since 1994, she has taught courses in satellite remote sensing and climate-change issues, and also co-founded and co-directed the Rutgers Climate and Environmental Change Initiative. Presently, she is a Research Professor in the Rutgers Department of Marine and Coastal Sciences, and she studies Arctic climate change and Arctic-global climate linkages. She and her husband circumnavigated the world in a sailboat from 1980-1985, including Cape Horn and the Arctic, during which her interest in weather and the Arctic began. (Email:

Lawrence (Larry) Hamilton is a professor of sociology at the University of New Hampshire. Since 1992, he has conducted interdisciplinary studies around the circumpolar North, supported by a series of grants from the U.S. National Science Foundation. Results from this work include case studies, technical analysis, and comparative overviews of resource-dependent communities in Alaska, Newfoundland, Greenland, Iceland, the Faroe Islands and Norway. He has been an active participant in many national and international working groups on the human dimensions of Arctic environmental change. Combining his Arctic and survey interests, some recent studies explore what the general public knows and believes about Polar Regions. (Email:

Bob Henson, who is probably the world's premier science writer in meteorology and climate change, is a full-time blogger on weather and climate change topics with Weather Underground. From 1990 through 2014, Bob was a writer/editor/media relations specialist for the University Corporation for Atmospheric Research/National Center for Atmospheric Research (NCAR) in Boulder, Colorado. Bob earned his Bachelor's degree in meteorology from Rice University in 1983, and went on to get a Master's degree in Journalism from the University of Oklahoma in 1988, where he engaged in a fair bit of storm chasing on the side. He has written many books on weather and climate change, including ”The Thinking Person’s Guide to Climate Change” and the number one textbook for 101-level college meteorology courses, Meteorology Today (11th edition). Bob is a contributing editor of Weatherwise magazine and has also written more than 50 articles for Nature, Scientific American, Discover, Sierra, The Guardian, AIR & SPACE/Smithsonian, and other media outlets.

Marika M. Holland is a Senior Scientist in the Climate and Global Dynamics Laboratory at the National Center for Atmospheric Research. Her research interests are focused on the role of sea ice in the climate system, including sea ice variability and change, ice-ocean-atmosphere interactions, abrupt high latitude climate change, and sea ice predictability. Dr. Holland has contributed to sea ice model developments for the Community Earth System Model (CESM) and has served as Chief Scientist for the CESM project. She has been a contributing author on the Intergovernmental Panel on Climate Change assessment reports and contributed to numerous other national and international assessments on the changing Arctic climate.

Henry P. Huntington (SIAN Co-lead) studies human-environment interactions in the Arctic, including subsistence hunting, traditional knowledge, Iñupiat Eskimo and Inuit knowledge and use of sea ice, and the impacts of climate change on Arctic communities and Arctic marine mammals. He has been involved in several international research programs and has served on studies by the National Academy of Sciences, the Council of Canadian Academies, and the National Petroleum Council. Huntington has made long trips in the Arctic by dog team, open boat, and snowmobile, and lives in Eagle River, Alaska. (Email:

Martin Jeffries is the Executive Director of the Interagency Arctic Research Policy Committee (IARPC). Prior to this appointment, Jeffries served as Program Officer and Arctic Science Advisor at the Office of Naval Research and as a Program Director at the National Science Foundation 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. While a professor at the University of Alaska Fairbanks, 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.

Brendan P. Kelly is Executive Director of the Study of Environmental Arctic Change (SEARCH) and Research Professor at the International Arctic Research Center, University of Alaska Fairbanks. A marine ecologist with a focus on sea ice environments, he has participated in and led collaborative research in the North Pacific Ocean, the Arctic Ocean, the Sea of Okhotsk, the Baltic Sea, and Antarctica. He has served as Deputy Director for Arctic Sciences, National Science Foundation; Assistant Director for Polar Science in the White House Office of Science and Technology Policy; and as a science adviser to indigenous organizations in Alaska. Currently, he serves on the National Academy of Sciences’ Polar Research Board and as a Senior Fellow at the Center for the Blue Economy, Middlebury Institute of International Studies at Monterey. Dr. Kelly received degrees in Biology from the University of California Santa Cruz (B.A.), the University of Alaska Fairbanks (M.S.), and Purdue University (Ph.D.). (Email:

Don Perovich is a Research Geophysicist at the Cold Regions Research and Engineering Laboratory in Hanover, NH and is an Adjunct Professor in the Thayer School of Engineering at Dartmouth College. He received a Ph.D. in Geophysics from the University of Washington. The central focus of his research is deceivingly simple to state: where does all the sunlight go? More precisely, how does the incident solar radiation interact with sea ice and snow? The interaction of sunlight with sea ice is intimately interrelated with the optical properties,  physical properties, heat budget, and ecosystem of the sea ice cover. A central element of his research is assessing the role of the sea ice albedo feedback in the Arctic climate system. He has participated in numerous Arctic field experiments including serving as the Chief Scientist of a year long field experiment studying the surface heat budget of the Arctic Ocean (SHEBA).
