My research program uses theory and observations to explore a wide range of processes in the formation of planets, from the birth of planet-forming discs to the long-term evolution of planetary systems.  Key science objectives are to investigate

  • how and when solids are processed in planet-forming discs;
  • how debris and disc systems acquire their morphologies;
  • whether there are multiple modes of gas giant planet formation and the frequency for which each mode occurs; and,
  • the observational consequences for planetary system evolution.

I am also a co-founder and co-director of the Outer Space Institute, an institute that takes a transdisciplinary approach to addressing major challenges in space. The scope of the institute is broad, but some focus areas include

  • space science-policy
  • space sustainability
  • light pollution from orbital infrastructure
  • space resource extraction
  • space debris
  • space weapons
