research interests

I specialize in using gravitational microlensing to detect and characterize exoplanets. Microlensing is able to probe the frequency and mass function of planets down to the mass of the Earth both for bound planets, with planet-star separations of roughly a few AU, as well as for free-floating exoplanets. Furthermore, microlensing is able to explore exoplanet demographics for bound and free-floating planets across a wide range of Galactocentric distances. I am currently an NPP fellow at JPL, where I am involved in several space-based microlensing missions, including Spitzer, K2's Campaign 9, and WFIRST. I also helped create and lead a high-resolution microlensing follow-up group at Caltech that focuses on using NIRC2 on Keck to complement space-based efforts.
