Large-scale structure, cosmology, evolution of galaxies
My field is the study of large-scale structure. In the past this has taken the form of large redshift surveys combined with careful analysis of nbody simulations. We have used the Keck telescope to obtain the world's largest sample of galaxies at redshift one, which is extremely useful for study of evolution of galaxies and the evolution of large-scale structure. For example, we can measure the dark energy parameter w through careful study of our data. The sample is equally useful to study the time evolution of the fine structure constant, alpha.
