His studies focus on observational investigation of the physics of galaxy evolution using large survey datasets from the Hubble Space Telescope, the Sloan Digital Sky Survey, PanSTARRS1, and Magellan. A few questions he's currently thinking about are: Why do some galaxies grow through star formation, while others long ago ceased to form new stars? How frequently do galaxies interact with each other? What are the effects of these interactions? View all of Eric's posts here.
