Emeritus Professor of Geophysics, University of Alaska Fairbanks PhD in Geophysics, University of Alaska Fairbanks. PhD in Geology, Moscow State University, Russia. Member of the American Geophysical Union, United States Permafrost Association, and the International Permafrost Association. Research interests involve scientific and practical aspects of environmental and engineering problems involving ice and permafrost. These include problems in the areas of soil physics, thermodynamics, heat and mass flow, and growth and decay processes that are associated with permafrost, subsea permafrost, seasonally frozen ground, and seasonal snow cover. I am also interested in the improvement of mathematical methods (analytical and numerical modeling) in geology and geophysics.
