Research Interests

I am engaged in a diverse program of research in astrophysics including experimental, observational, and some theoretical components.
Historically, my efforts have been concentrated in X-ray spectroscopy of astrophysical sources, but more recently I have moved into experimental cosmology. I am currently the Deputy Project Director and the Camera Lead Scientist for the Large Synoptic Survey Telescope (LSST) project, which will survey half the visible sky every few nights and provide a sensitive map of the distribution of dark matter in the local universe (z < 1). The statistical properties of the dark matter distribution provide sensitive constraints on the cosmological expansion history, and thus the nature of the mysterious dark energy which dominates the energy density of the universe.
