Research

I am a planetary scientist and astrophysicist who researches extrasolar planets in a wide variety of contexts.  Topics I have explored include planet detections, planet formation, planet death, free-floating planets, planets in binary star systems, and planets in different parts of the Milky Way galaxy.  My current research focus aims to answer some of the biggest mysteries regarding the fate of extrasolar planets and how they can "pollute" very old stars known as white dwarfs.

Career

I attained my undergraduate degree at Yale University and I conducted my graduate research in the Department of Astrophysical and Planetary Sciences at the University of Colorado at Boulder with Philip J. Armitage.  Subsequently, I was a Postdoctoral Associate in the Department of Astronomy at the University of Florida, and worked with Eric B. Ford on the dynamics and evolution of planetary systems.
