About Rick

I am a geophysicist with interests in Earth and environmental science, including Earth structure, earthquakes, volcanos, oceans, and glaciers. My research has drawn significantly from seismological field studies in western North America, Italy, and Antarctica. I also have strong teaching and research interests in geophysical inverse and signal processing methods and am the lead author on the widely used reference volume and textbook "Parameter Estimation and Inverse Problems" (Aster, Borchers, and Thurber, 2018).
