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, security, and disarmament
