Curriculum Vitae:

Margaret Glasscoe

Margaret Glasscoe is a Member of the Technical Staff in the Solid Earth Group at the Jet Propulsion Laboratory, California Institute of Technology. She is completing her PhD on the topic of numerical simulations of fault interactions at the University of California, Davis. She has experience working with a number of modeling codes, including viscoelastic finite element models (the JPL developed Geophysical Finite Element Simulation Tool, GeoFEST, in particular). Her research includes modeling deformation of the Earth’s crust to study postseismic response to large earthquakes, numerical models of the rheological behavior of the lower crust, and simulations of interacting fault systems.

  • MS in Geology, University of California, Davis (2003)
Research Interests
  • Crust-mantle interaction in southern California
  • Development of the "drip" beneath the Transverse Ranges, southern California
  • Block rotations of southern California crust and the development of the LA Basin
  • Deformation in southern California and driving mechanisms
