Doug Roberts Adjunct Associate Professor

Doug Roberts' research is involved in several investigations to measure the motion of warm gas around the supermassive black hole that is believed to exist in the center of our Galaxy. Recently, Dr. Roberts has participated in world-wide campaigns to observe the supermassive black hole at the center of the Galaxy for hourly variability, which probes physics very near the black hole. Using his expertise of the Center of the Galaxy, Dr. Roberts has worked as a science adviser for the 2002 Discovery Channel show entitled Unfolding Universe. Additionally, Dr. Roberts uses radio telescopes such as the Very Large Array (VLA) to investigate the interaction of the shells of exploded stars (supernova remnants) with molecular clouds, which are the stellar nurseries where new stars are formed.

Roberts also works with the WorldWide Telescope (WWT) team at Microsoft Research. Roberts uses scientific visualization, including WWT, to interpret his own research and communicate it to professional and public audiences. As a member of the WWT team, he is a liaison between Microsoft Research and the planetarium, astronomical research and informal learning communities. He is keen on connecting research and outreach activities and developing the visualization innovations necessary to bring them together.
