Research Interests

I study the recently-discovered class of extrasolar planets called "super-Earths", whose sizes are between that of Earth and Neptune.  There are no planets like them here in our own Solar System, yet we have discovered thousands orbiting other stars.  As a result, what these planets are like and how they came to exist is an enormously exciting mystery.  Given their vast numbers, I tackle these questions by applying models describing the entire super-Earth population to the data from the Kepler Mission; through the power of advanced statistical methods, I am able to constrain different scenarios for how these planets could have evolved to their current states since formation.
