I am interested in the dynamical interactions between planets and debris disks, both in exoplanet systems and in our own Solar System. In our Solar System, the structure of the Kuiper belt gives information about the migration history of the giant planets. In exoplanet systems, we can use the structure of debris disks (dusty disks around stars made by colliding asteroids) to find exoplanets that would otherwise be invisible.
I am a dynamical modeler with a strong background in observational astronomy. Lately much of my work involves "observing" imaginary planets and dust using computer code, but I still get a lot of opportunity to compare my predictions with real data from real telescopes.
