Current Research Projects

Most of my research projects involve observational astronomical interferometry, using the Very Large Telescope Interferometer, the CHARA Array, the Palomar Testbed Interferometer (PTI), the Keck Interferometer, and the IR/Optical Telescope Array (IOTA). Specific topics include:

Basic parameters (radius, temperature, mass) of Giant and Supergiant Stars
Narrow-angle astrometry (fields of <30 arcseconds, with microarcsecond measurement precision)
Stellar Rotation, including direct measures of oblateness of rapidly rotating stars
Young Stellar Objects
Carbon stars
Cataclysmic Variables
Mira Variables
Spectroscopic Binaries
Active Galactic Nuclei

In addition to astronomical interferometry, I am working on planetary detection through ground-based transit observations.

Also available are online versions of published papers and presentations.
