About Rick

I am a geoscientist with interests in geophysics, seismological imaging and source studies, and Earth processes encompassing earthquakes, volcanoes, glaciers, oceans, and geology. My research has drawn from significant seismological field studies in western North America, Italy, and Antarctica. I 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, 2011; 2018).
