I am currently a third-year Astronomy/Astrobiology PhD student at the University of Washington, where I study the habitability of extrasolar planets around the lowest-mass M dwarf stars. Together with my advisor, Dr. Rory Barnes, I have been looking at several aspects of the evolution of planets in the habitable zone of M dwarfs, including tidal migration, early runaway greenhouses, and atmospheric escape. I am also working with Kepler data on short-period exoplanets, trying to pin down the rate of tidal evolution as a function of planet size and composition.
