Research Interests:

My research focuses on problems in astrophysics and particle physics that arise in cosmology. I am interested in the study of the large scale structure of the universe and how it forms -- this is structure as traced by several different objects and techniques, including galaxies, Lyman-break objects, quasars, quasar absorption systems, and gravitational lensing. Research in these areas involve an interplay between understanding the physics that govern properties of some of these objects and the development of new statistical tools that exploit these properties. I am also interested in the application of modern ideas in particle physics to cosmology, or conversely, the use of cosmological observations to probe new physics -- dark matter candidates and their detection, inflation and reheating, and the physics of vacuum energy or quintessence that might be causing an apparent acceleration in the expansion rate of the universe. Lastly, I am very interested in new observational windows at the intersection of astronomy and particle physics, involving high energy cosmic rays and neutrinos.
