Professor, Physics, Applied Physics & Astronomy

I am a participant in the Sloan Digital Sky Survey, which will image 10,000 square degrees of the north galactic cap in five optical filters over the next five years. Additionally, we will obtain a million spectra of the galaxies (and hundreds of thousands of QSOs and stars) detected in the imaging survey. My current research is primarily related to understanding the structure of our own galaxy through using A stars as tracers of the galactic halo, and using photometrically determined metallicities of main sequence F-K stars to determine whether the thick disk is chemically distinct from the thin disk and galactic halo of our galaxy. I hope that these studies will contribute to our understanding of how the Galaxy formed. I have worked in many areas of astronomy over the course of my career. I did my PhD with the Berkeley Automated Supernova Search, which measured the supernova rates as a function of supernova type in Virgo-distance galaxies; and the Supernova Cosmology Project, which is measuring the cosmological parameters Omega and Lambda using the light curves of distant supernovae. I have published papers in diverse areas of galactic and extragalactic astronomy, including: supernova phenomenology, measuring cosmological parameters from supernovae, galaxy photometry, color selection of QSOs, properties of stars, and the structure of our galaxy.
