RESEARCH: Mark works on event location, surface wave magnitude estimation, and event discrimination. He spends quite a bit of time on field projects to acquire seismic data from explosions and other sources. Recent large field projects include the Arizona Source Phenomenology Experiment and the Alaska Frozen Rock Experiment.

EXPERIENCE: Mark joined Weston Geophysical in 2002 after working at Southern Methodist University as a research geophysicist. At SMU he developed thermal and structural models of geothermal fields in the U.S. by modeling gravity, high-resolution aeromagnetics, heat flow, and reflection seismology. Before that, Mark spent time at the University of Arizona developing seismic software and constructing a database for a seismological deployment in the Andes Mountains of Chile and Argentina.

EDUCATION: In May 1999, Mark received a Geophysics/Geology B.S. degree from Southern Methodist University where he originally began his work on geothermal research. Mark received an M.S. degree from the University of Arizona in December 2000 under Dr. George Zandt. His thesis work determined the magnitude and orientation of crustal seismic anisotropy in the Altiplano-Puna Volcanic Complex of the Bolivian/Argentinian/Chilean Andes.
