My research deals with understanding the nature and evolution of massive luminous stars, those of the hottest spectral types. These are primarily O-type and Wolf-Rayet stars found in the Galactic plane and in other galaxies. In starburst galaxies, the numbers of these stars are sufficient that they may be detected collectively, even in those objects at very large redshift. I am currently emphasizing photometry and spectroscopy of luminous stars in our Galaxy in the near infra-red, at about two microns, where the absorption of the intervening Galactic dust is low.
