Professor, Earth & Planetary Sciences, UC Davis
Visiting Professor, Earth & Planetary Sciences, Harvard


  • Collisions in the Solar System
    Sarah's research focuses on the formation and evolution of planetary bodies. Her primary techniques are shock wave experiments and numerical simulations of planetary collisions.
  • New Shock Compression Lab
    at UC Davis

    Rendering of the UC Davis lab, scheduled for completion in December 2015. The Shock Compression Laboratory at Harvard will be moved when the new lab is ready.

    The lab is accepting new students and postdocs for Fall 2015.

  • Z Experiments
    Sandia's Z Machine can launch flyer plates up to 40 km/s. Sarah's group is part of a Fundamental Science User Experiment on Z to study shock-induced vaporization of mantle minerals.
  • Laser Experiments
    The NIF laser at LLNL can reach the pressures and temperatures reached in the center of planets and during giant impact events. Sarah is a member of a NIF Discovery Science team to measure the melting curve of iron under Super-Earth conditions. Sarah's group also uses the Janus laser at the Jupiter Laser Facility to obtain equation of state data on planetary materials at high pressures and temperatures.
  • Resources for other researchers

    Analytic collision outcome model
    Animations and graphics of planetary collisions
