Teaching
Richard C. Aster, Professor of Geophysics

I generally teach graduate/advanced undergraduate courses in inverse theory, seismology, and data processing and analysis, as well as being actively involved in public lectures and other general outreach activies. I am a strong proponent of using Matlab for teaching and research calculations.

In association with the IRIS Education and Outreach Program and colleagues from NM Tech and elsewhere, I coordinate a yearly May 1-week orientation for the IRIS Undergraduate Intern Program, hosted at the on-campus PASSCAL Instrument Center.

Here are some recent courses that I have taught at NM Tech:

Spring 2008, Spring 2006, Fall 2003, Spring 2000
GEOP 523: Theoretical Seismology
Linear elastic wave theory, including reflection and refraction of elastic waves, propagation of body and surface waves, free oscillations, seismic rays in a spherically-stratified earth, and earthquake mechanisms.

Spring 2007, Fall, 2005, Fall 2004, Spring 2003, Spring 2002
GEOP 529: Geophysical Inverse Methods
Theory and practice of inverting geophysical data to obtain models. Brian Borchers, Cliff Thurber, and I have also authored a textbook, Parameter Estimation and Inverse Problems (Elsevier, 2004) used in this course and at many universities internationally.

Spring 2005, Spring 2004, Fall 2002, Spring 2001
GEOP 505: Data Processing and Analysis
An introduction to methods for reducing and analyzing temporal and spatial data with an emphasis on geophysical problems. Topics include characterization of linear systems in continuous and discrete time, Fourier analysis, spectral estimation, convolution and deconvolution, filtering, the z and Laplace transforms, analysis of multidimensional and multichannel data.

Spring 2002
GEOP 570: Current Topics in Earthquake Seismology
An overview of current research topics in earthquake seismology with an emphasis on the critical review of recently published papers and preprints. The 2002 class covered volcano seismology.

Fall, 2007
GEOP 571: Evolution of the Lithosphere
An overview of current research topics in geophysical and geochemical investigation of the continental lithosphere.
