Searching for the First Galaxies
and Studying Their Impact on Reionization

I study the processes by which galaxies evolve through time, from extremely small systems in the early universe, to form large galaxies today like our own Milky Way. I discover these galaxies using imaging from space telescopes, most recently from the CANDELS survey, the largest Hubble Space Telescope program ever. Members of my group and I study these images to both discover and characterize distant galaxies, and we use the largest ground-based telescopes to follow them up spectroscopically. I am also heavily involved in the HETDEX project, and we are working to build the next great extragalactic legacy field in a 24 square degree region of the HETDEX survey (the HETDEX/SHELA field) where we are amassing imaging from the optical to infrared from both ground and space-based telescopes.
