Research

My research focuses on planet formation and dynamics. I have worked on terrestrial planet formation, dynamics of extra-solar planetary systems, dynamical instabilities in giant planet systems, tidal evolution, and searches for Near Earth Objects.

NEW (June 2018):We've made a series of 12 videos to explain new ideas about planet formation and why the Solar System looks different than most extrasolar planet systems. They are called the MOJO videos are are on Youtube. I wrote this blog post to introduce them (which includes links to all 12 videos).

ALSO NEW: I have started putting many of the animations I've made (along with a description) up on my Youtube channel. Feel free to use them in talks/classes/whatever.

Below are descriptions of a few recent projects that I'm excited about and that I have illustrated with movies (most of which I made myself). Feel free to download the movies for use in talks, etc, and please reference the appropriate papers.

  • Terrestrial planet formation and water delivery in the Solar System
  • Debris disks as signposts of terrestrial planet formation
  • Accretion of terrestrial planets with migrating giant planets
  • The GRAND TACK model for the origin of the inner Solar System
  • Generalized Milankovitch Cycles: climate models of Earth-like planets with oscillating orbits


    • Given that I don't update this page very frequently, the best way to learn about my most recent research is to look at my publication list or my CV, which are more frequently updated.
