Transiting Extrasolar Planets
Searching for secondary eclipses of Hot Jupiters in order to probe their albedo, heat redistribution efficiency, and atmospheric composition.
Examining parameter variations to probe for lower mass, possibly Earth-sized planets in those systems.
Disentangling the effects of limb darkening and atmospheric absorption versus wavelength in order to use ground-based transit data to probe the atmospheric properties of transiting extrasolar planets.
Low-Mass Eclipsing Binaries
Attempting to shed light on the problem of inflated radii in low-mass stars. Are stellar models wrong, or are the observed stars inflated by being in short-period binary systems?
Discovered 30+ new low-mass (M < M☉), long-period (P > 10 days) eclipsing binaries via the Kepler mission.
Obtaining follow-up multi-color light and radial-velocity curves of low-mass eclipsing binaries to accurately measure their mass, radius, and effective temperature.
Multi-Wavelength Modeling of Microarcsecond Astrometry
Worked on modeling the multi-wavelength astrometric motions of various binary stars. Was a project for the now-canceled Space Interferometry Mission (SIM).
Discovered a novel technique to directly determine the absolute inclination and spatial orientation of single stars via multi-wavelength astrometry.
Working on modeling the multi-wavelength astrometric signature of extrasolar planets.
Near Contact and W Uma Stars and Thier Formation
Studied many near-contact and contact eclipsing binary systems and theories of their formation.
