Overview
Seismology research and machine learning applications to earthquakes across Texas, New Mexico, California and Finland. Current projects include earthquake source characterization, mitigation of injection induced seismicity, using near-surface geophysics to study climate change, and geothermal well risk monitoring. Field campaigns in Texas and New Mexico, and opportunities to work with multiple geophysical techniques.Publications

Current Openings
I am recruiting a postdoc in near-surface/critical-zone science!The postdoctoral researcher will work on projects related to analyzing the upper 50-100 m of the earth’s surface and understanding stress conditions within the critical zone. Research topics of interest include, but are not limited to, using active seismic and GPR data to map subsurface structures along the Gulf Coast of Texas, monitoring ground water levels in west Texas, and understanding pressure/stress in fractured bedrock. The researcher will also be encouraged to help write research grant proposals and conduct independent research.

Study Maps Stress Changes Around Fault Activated by Hydraulic Fracturing
Researchers were able to observe stress changes before and during an earthquake induced by hydraulic fracturing in Alberta, Canada, with the help of a phenomenon called seismic anisotropy.
