    RESEARCH INTERESTS:

      Over my career, my research has spanned a variety of seismological subjects, including earthquake source modeling, seismotectonics, earthquake hazards, and nuclear treaty monitoring research (seismic event detection, location, and discrimination). I have also studied hydroacoustic wave propagation and explored military applications of seismology. Since arriving at the University of Texas at El Paso in January 2002, I have been able to expand my research goals and pursue projects that were inconceivable to me just a few years ago.

      My current projects include: seismic hazard analyses through the study of historic and recent earthquakes in the Bhutan Himalayas and Cape Mendocino, California; determining Earth structure from analysis of a data recorded by a temporary seismic network in Bhutan; studying the earthquake rupture processes of the Nov. 8, 2002 Denali Fault, Alaska earthquake; and studying regional wave propagations from mining explosions in eastern Arizona for nuclear explosion monitoring. I plan to continue developing a strong research program at UTEP. Thus, I am also seeking funding for the following: improving seismic techniques utilizing Wavelet Transforms; studying earthquake rupture processes of large earthquakes to understand the earthquake cycle; improving regional seismic detection, location, and discrimination; studying the evolution of the Rio Grande Rift near El Paso, TX using both passive seismic data and geological investigations; increasing field capabilities through the purchase of broadband seismometer systems; and further developing field projects in the Bhutan Himalayas and in the Alps in Austria.
