I am the NASA Exoplanet Science Institute (NExScI) Deputy Director and the NASA Exoplanet Archive task lead. NExScI is the science operations and analysis center for NASA's Exoplanet Exploration Program . We provide tools and archives for the exoplanet community, administer the Sagan program of fellowships and workshops, and support Kepler and the Large Binocular Telescope Interferometer and administration of the NASA Keck telescope time.
The NASA Exoplanet Archive collects and serves public data to support the search for and characterization of exoplanets and their host stars. The data include published light curves, images, spectra and parameters, and time-series data from surveys that aim to discover transiting exoplanets. Tools are provided to work with the data, particularly the display and analysis of transit data sets from Kepler and CoRoT. All data are validated by the Exoplanet Archive science staff and traced to their sources. The Exoplanet Archive is the U.S. data portal for the CoRoT mission.

Millimeter Interferometric PolarizationThis project involved the installation of adjustable polarizers on the Owens Valley Radio Observatory millimeter array. Used as quarter-wave plates, these polarizers can measured the linearly polarized emission at 3 mm.
