My current research interests focus mainly on how galaxies (including the Milky Way) form and evolve into the objects we see today and how the interstellar gas within galaxies is collected to form stars (including the Sun and Solar System). In particular, I work on the earliest stages of star formation, as well as the dynamics, structure and evolution of the Milky Way and other galaxies. Items of current active interest include trying to understand the nature of dark matter on galactic scales, particularly in dwarf galaxies and in the outer parts of the Milky Way. I am also working on how the diffuse interstellar medium generates star-forming giant molecular clouds in different environments to unravel the basic physics of star formation on galactic scales. We operate an array of twenty-three millimeter-wave radio telescopes as part of the CARMA Array, near Bishop, California. We are building the Allen Telescope Array, a new type of radio interferometer of 350 dishes using commercial satellite dish technology to synthesize an aperture of 10,000 square meters for use at centimeter wavelengths.
