I am a fourth year PhD student in Astronomy at the University of North Carolina at Chapel Hill.  I am interested in astronomical instrumentation, stellar populations, and exoplanets.  

I currently research binary stars using data from the Robo-AO system. This includes high-resolution observations of every Kepler Object of Interest star and a comprehensive binary census of every star within 25 pc. With unparalleled efficiency, the robotic AO system can perform these large AO surveys that were previously impractical. I also work on the design and construction of a diffraction limited NGS-AO system, SRAO, for the SOAR telescope, a semi-autonomous instrument that will, along with Robo-AO, provide all-sky robotic AO coverage.
