I am interested in extrasolar planets and their formation. In order to study these objects and processes, I am seeking to advance astronomical instrumentation and observational technique. Particularly interesting are indirect and direct techniques for detecting extrasolar planets with adaptive optics, coronagraphy, and interferometry. I am also studying dust disks around main sequence stars. High-contrast observations of circumstellar debris can reveal signatures of planet formation.
