ture and function in the north Alaskan and Beringian Arctic and in the Chihuahuan Desert.


John Walsh is a President’s Professor of Global Change at the University of Alaska, Fairbanks. He is also the Director of the Cooperative Institute for Arctic Research and the Center for Global Change at the University of Alaska. He received his Ph.D. in Meteorology at the Massachusetts Institute of Technology in 1974, and served for 30 years on the faculty of the Department of Atmospheric Sciences, University of Illinois, Urbana. Dr. Walsh’s research interests include the climate of the Arctic, especially interactions between the atmosphere and polar surfaces; extreme weather events as they relate to climate; and the variability of the cryosphere. He was a lead author of the Arctic Climate Impact Assessment (2001-2005), and is a lead author for the Polar Regions chapter of the Intergovernmental Panel on Climate Change’s ongoing assessment. He has been a committee member of the Arctic Climate System Study and the Study of Environmental Arctic Change. He is a Fellow of the American Meteorological Society.

NRC Staff

Paul Cutler (Study Director) is a senior program officer for the Polar Research Board of the National Academies. He directs studies in the areas of polar science and atmospheric science. Before joining the Polar Research Board staff, Dr. Cutler was a senior program officer in the Academies’ Board on Earth Sciences and Resources, where he directed the Mapping Science Committee and studies in Earth science and geographic information science. Before joining the Academies, he was an assistant scientist and lecturer in the Department of Geology and Geophysics at the University of Wisconsin, Madison. His research is in glaciology, hydrology, meteorology, and quaternary science, and he has conducted fieldwork in Alaska, Antarctica, arctic Sweden, the Swiss Alps, Pakistan’s Karakoram mountains, the midwestern United States, and the Canadian Rockies. Dr. Cutler received an M.Sc. in geography from the University of Toronto, and a Ph.D. in geology from the University of Minnesota.


Matthew L. Druckenmiller (Science and Technology Policy Graduate Fellow) was a visiting fellow with the Polar Research Board of the National Academies during Fall 2005. Prior to his fellowship, he attended the University of Alaska, Fairbanks, where he researched glacier volume changes throughout Alaska and western Canada using small aircraft laser altimetry. His research interests include interdisciplinary environmental change studies in the Arctic, remote sensing of the cryosphere, and carbon sequestration. Mr. Druckenmiller received a B.Sc. in environmental systems engineering and an M.Sc. in geo-environmental engineering from The Pennsylvania State University, where he investigated geologic carbon sequestration in brine.


Rachael Shiflett (Senior Program Assistant) is a senior program assistant with the Polar Research Board. She received her M.Sc. in environmental law from Vermont Law School in 2001 and will complete her J.D. at Catholic University in May 2007. Ms. Shiflett has coordinated National Research Council studies that produced the reports Vision for the International Polar Year 2007-2008, and International Polar Year 2007-2008 Report of the Implementation Workshop. Her research interests include the Endangered Species Act, the Marine Mammal Protection Act, and the National Environmental Policy Act.
