Hello!

I'm a first-year Astrophysics PhD student at Princeton University, interested in understanding how planetary systems form and evolve (and, previously, galaxies). Before graduate school, I studied Physics at the University of Toronto on a Schulich Leader Scholarship. If you’d like to connect, feel free to reach out!

Research Interests

  • Exoplanets

    There is now a large population of known exoplanet systems. I’m interested in leveraging a variety of tools (including numerical simulations, dynamics theory, and statistics) to draw conclusions about the formation and subsequent evolution of these planetary systems.

  • Planet formation

    Many open questions remain in planet formation. Specific interests include understanding the outcomes of the giant impact phase of planet formation, as well as the formation of planetary systems trapped in chains of resonances.

  • Dynamics

    I’m also interested in understanding the dynamics that underpin the evolution of planetary systems. For instance, I’ve worked towards understanding the mechanism by which multiplanet systems destabilize.
