1) Developed a widely-used empirically-based seismic source model for underground nuclear explosions.

2) Made a number of published contributions in the study of underground nuclear explosions, including observed wave propagation, statistical treatment of magnitudes, and detection and location methodology.

3) In one of the first applications of fractals to earthquakes, showed the relation of b-value, stress inhomogeneity, and liklihood of large ruptures.

4) Authored a complete reference book on mathematical curves and surfaces (CRC Standard Curves and Surfaces).

5) Defined 3-D image resolution based on the point-reflector model for seismic exploration, leading to a description of the performance of various 3-D seismic survey configurations.

6) Analyzed and reported the seismicity in the vicinity of Yucca Mountain, Nevada, the site of the USA's potential underground nuclear waste storage, for thirteen years.
