• Analyzing induced seismicity to assess seismic hazard, support risk mitigation strategies, and optimize stimulation and completion efficiency.
• Extract earthquake source parameters—including magnitude, focal mechanism, and stress drop—from DAS, geophones, and seismometers; develop and apply rupture models to characterize fault behavior.
• Design and implement algorithms for real-time seismic hazard assessment using physics-based modeling, statistical analysis, and machine learning approaches.

Required Qualifications

• Master’s or Ph.D. in Geophysics, Seismology, Applied mathematics or a related field.
• Strong proficiency in earthquake source analysis, including moment tensor inversion, stress drop estimation, and stress inversion. Experience with DAS-based earthquake source characterization is a plus but not required.
• Demonstrated ability to develop analytical and numerical models for interpreting strain and strain rate from fiber-optic DAS data during hydraulic stimulation and geothermal production.
• Experience integrating seismic observations with Thermo-Hydro-Mechanical-Chemical (THMC) models to evaluate seismic and aseismic slip processes.
• Proficiency in Python for seismic data processing, including scripting, tool development, and algorithm implementation; familiarity with Linux-based computing environments.
