Research Interests

My main area of research is Astrometry. Research interests in Astrometry at Yale lie primarily in the fields of absolute and relative proper motions , stellar parallaxes, binaries and instrumentation to improve the accuracy of astrometric observations with applications to Star Clusters, Galactic Structure, and Space Astrometry.
