Jason M. Amundson, Ph.D.

Jason M. Amundson, Ph.D.

Professor of Geophysics

I have a background in glaciology and geophysics. My research focuses on tidewater glaciers and glacier-ocean interactions, and I am especially interested in the ways that glaciers interact with other Earth system components. I teach the introductory physics courses as well as upper division courses in Earth's climate and glaciology.

Sonia A. Nagorski, Ph.D.

Associate Professor of Geology

My background is in environmental geochemistry, and my research has focused primarily on a variety of contaminants in aquatic systems. I teach classes on Earth's geologic history, physical geology, natural hazards, geomorphology, and mineral and energy resources and environmental impacts. At UAS I devote my efforts to training and inspiring undergraduates to work creatively and effectively in the environmental sciences, preparing them for meaningful careers that benefit the Earth and society.
