Current Research

My research is primarily focused on observational astronomy and the study of the evolution of galaxies in particular, including local Low Surface Brightness and star forming galaxies at moderate redshifts. Current projects investigate dust and morphological properties of Lyman break and disk galaxies at redshift z~2. These projects utilize a wide variety of public multi-wavelength (UV to far-IR) imaging and spectroscopy survey data. The multi-wavelength data allow for detailed studies of the spectral energy distributions of the target galaxies to investigate their star formation histories and therefore their evolutio. Additionally, I am involved in projects aiming on the study of large scale structures investigating large concentrations of quasars, so called Large Quasar Groups (LQGs). These LQGs exist on scales of several 100 Mpc and represent the largest concentrations of matter in the Universe. My work is funded through grants from NASA (e.g. Kentucky Space Grant Consortium) allows me to involve undergraduate and graduate students in these projects.
