Professor of Geophysics and Department Head, Colorado State University

I am an Earth scientist with broad interests and publications in geophysics, earthquakes, seismological imaging, glaciology, seismic coupling between the oceans, solid Earth, and atmosphere, and volcanology. My work has included significant field research in western North America, Italy, and Antarctica. I have served in a number of community and leadership capacities, including as president of the Seismological Society of America (2009-2011) and, currently, as Department Head of Geosciences in the Warner College of Natural Resources at Colorado State University.
