Doug Roberts

Adjunct Associate Professor
PhD, University of Oklahoma, 1992

Senior Director of Digital Technologies, Adler Planetarium & Astronomy Museum

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) and Green Bank Telescope (GBT) 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. At Northwestern University, as the Architect for Visualization, Dr. Roberts manages an advanced visualization lab, which supports researchers and educators use stereoscopic and ultra-high resolution displays to view complex data sets. This visualization experience is put to use at Adler where he is the Director of the Space Visualization Laboratory.
