Research: Formation and evolution of exoplanet systems

I am a NASA Postdoctoral Fellow at the Center for Exoplanets and Habitable Worlds at the Pennsylvania State University. My research interests include planet formation, the dynamical evolution of planetary systems, and the origin of volatiles (water and atmosphere) in super-Earths. Super-Earths are a type of exoplanet with a size between that of Earth and Neptune. While there are no super-Earths in the solar system, the Kepler mission has revealed that they are the most common type of planet in the Galaxy, with thousands already discovered.

I conduct mainly theoretical work using computer simulations to model the formation of planetary systems. I normally use Rebound or Mercury codes for N-body simulations, and the Pencil Code for hydrodynamic simulations. I enjoy programming and I have an interest in scientific computing.
