EES Research Opportunities

Prof. Cynthia EbingerGeophysics and Active Tectonics Research (GATR)

Team:  Carolina Hurtado-Pulido, Martin Musila, Garrett Sullivan, Eduardo Arzabala (research students); Sophie Aber and Samia Sabir (lab assistants);  Samantha Hilburn, Hayden Holcomb, Emily Kraus, Kyle Campbell, Owen Williamson, Josh Ben-Dashan (undergrad researchers)

With abundant help from Dr SarahJaye Oliva (U Vic) and Dr Francesco Civilini (CalTech) 

Goals:  Our team of graduate and undergraduate researchers use seismic and potential fields methods, signal processing and geospatial tools to probe fundamental Earth processes. Our focus is magma-fault interactions within the crust and mantle at rifts and hotspots, both active and ancient. We apply methods and results to explore hydrothermal energy potential and to evaluate earthquake and volcanic hazards.

Student Opportunities:  We seek students interested in the use of geophysical and satellite-based tools to determine the rates of tectono-magmatic processes and image subsurface structure for hazard and energy evaluation.  We have active seismic acquisition programs in Rwanda, Kenya and Ethiopia, New Zealand, Ecuador.  Undergraduates keen to acquire command-line programming and analytical skills are welcome.
