Research Interests

Although work focuses on impact crater formation, I am interested in using numerical modeling to approach a range of other topics:

  • Surface Processes

  • Solar System Evolution

  • Plate tectonics

  • Comparative Planetology (Notably icy vs rocky worlds)

  • Mantle convection


  • Ice Shell Structure of Ganymede and Callisto Based on Impact Crater Morphology
