Research
In collaboration with graduate students, I have been researching in the area of statistical and transform methods for seismic data processing, waveform imaging and inversion in applied and global seismology. Over the past ten years, we have become recognized for the development of algorithms for multi-dimensional seismic data reconstruction, de-noising and the application of sparsity promoting methods to seismic data processing. We are currently studying problems of optimal acquisition design for simultaneous source acquisition, imaging, and full waveform inversion.

Courses
GEOPH 326 - Seismic Imaging of Earth's Interior
Use of reflection and refraction seismology to image the Earth's interior, including application to environmental assessment, mineral and hydrocarbon exploration, geothermal energy, and tectonics; study of current technologies used to acquire, image, and interpret 2D and 3D data sets. Real data sets and computer assignments will be used to produce seismic images of the subsurface. Prerequisite: MATH 215 or 209 or 315 or 317 or MA PH 351.
GEOPH 426 - Signal Analysis in Geophysics
Application of time-series analyses and image-processing techniques to large geophysical data sets; sampling and aliasing of signals; one- and two-dimensional Fourier transforms; the Z transformation; spectral analysis, filtering, and deconvolution; application of 1D and 2D filtering to geophysical data analysis, processing and decomposition. Prerequisites: MATH 311, GEOPH 326, PHYS 234 or equivalent. Note: credit may only be obtained for one of GEOPH 426 and GEOPH 526.
GEOPH 431 - Geophysical Inverse Theory
Quantitative methods to determine the physical properties of the Earth from indirect geophysical observations; formal treatment of geophysical inverse theory; topics include linear and nonlinear inverse problems, regularization techniques, model norms and misfit, tomography, and case histories of interpretation and analysis. Prerequisites: MATH 311. Note: credit may only be obtained for one of GEOPH 431 and GEOPH 531.
GEOPH 526 - Signal Analysis in Geophysics
Application of time-series analyses and image-processing techniques to large geophysical data sets; sampling and aliasing of signals; one- and two-dimensional Fourier transforms; the Z transformation; spectral analysis, filtering, and deconvolution; application of 1D and 2D filtering to geophysical data analysis, processing, and decomposition. Note: credit may only be obtained for one of GEOPH 426 and GEOPH 526. Prerequisite: Consent of instructor.
GEOPH 531 - Geophysical Inverse Theory
Quantitative methods to determine the physical properties of the Earth from indirect geophysical observations; formal treatment of geophysical inverse theory; topics include linear and nonlinear inverse problems, regularization techniques, model norms and misfit, tomography, and case histories of interpretation and analysis. Note: credit may only be obtained for one of GEOPH 431 and GEOPH 531.
