John is a faculty member of the Nevada Seismological Laboratory and the Dept. of Geological Sciences and Engineering in the Mackay School of Earth Sciences and Engineering, College of Science at the University of Nevada, Reno.

''The goal of my research is to accurately image and characterize subsurface structures and conditions in seismically difficult areas, with high-resolution experiments. I constrain these observations with independent geophysical and geological data. The seismic characterization, imaging, tomography, and monte-carlo optimization techniques I develop improve the productivity of resource exploration and development, and of hazards assessments. In particular I try to describe the characteristics of earthquake faults and of sites in order to mitigate seismic hazards to life and property; and seismically image geothermal resources.''

Key Words: geophysics, seismology, resource exploration and development, seismic reflection, geophysical imaging and inversion, tomography, modeling, scientific visualization, earthquake hazards and zonation, parcel mapping, ReMi, tectonics.

John teaches:
