Aaron Roodman is a professor and chair of the Particle Physics & Astrophysics department at Stanford’s SLAC National Accelerator Laboratory. Trained in experimental particle physics, he spent two decades studying differences between Matter and antiMatter, before turning his research to astrophysics and cosmology. Roodman’s current research focuses on the study of Dark Energy using images from large optical telescope surveys, such as the Dark Energy Survey. He is also responsible for the assembly and testing of the world’s largest digital camera now under construction for the upcoming Large Synoptic Survey Telescope.
