I have 30 years of experience, and specialize in the field of Geophysics with specific knowledge in the areas of seismology, earthquake engineering, and environmental geophysics. I have published on such topics as intraplate earthquakes, local site effect, groundwater contamination characterization, and tomographic imaging. Current research concentrates on numerical modeling and imaging with electromagnetic, acoustic, and seismic waves for exploration, military, geotechnical, environmental, and biomedical engineering applications.
