Research Interests

Geophysics || Fracture Mechanics || Geodesy || Tectonophysics

My research combines geology with fundamentals of physics, mathematics, and computer science to learn about how the Earth deforms in response to tectonic stresses. Earthquake-generating faults follow physical laws that can be quantified and mathematically modeled, consequently much of my recent research has focused on creating 3D mechanical models of the most complex portions of southern California including the Los Angeles and Ventura Basins. I also use modern satellite geodesy techniques including GPS and InSAR to measure defomation of the surface of the Earth.

Because this type of work is quantitative and involves processing very large data sets, computer programming is a key component to my research. If you are a student and this type of research sounds interesting, please see my student opportunities page. Check out my research page for more details about my recent and ongoing projects.

Is this work useful to society?

Understanding surface deformation and fracture mechanics is not only of academic interest. For example, fracture mechanics and satellite-based surface deformation studies are commonly used to better understand numerous problems of societal interest including:

  • Earthquake hazards / Earthquake potential
  • Flow of fluids (water/oil/gas/fracking fluids) in the subsurface
  • The viability of peteroleum reservoirs
  • Safety of Dams and other engineered structures
  • Failures related to sinkholes, mine collapses, etc...
  • Volcano activity and predictions of volcanic eruptions
  • Monitoring and prediction of landslides and other land movements
