Derek Hoiem is an associate professor Computer Science at the University of Illinois at Urbana-Champaign, since January 2009. Derek received his PhD in Robotics from Carnegie Mellon University, and completed a postdoctoral fellowship at the Beckman Institute. Derek's primary research goal is to model the physical and semantic structure of the world, so computers can better understand scenes from images. In particular, he researches algorithms to interpret physical space from images and to relate objects to their environment and to each other. Example applications include creating 3D models of scenes and objects from one image, photorealistic rendering of object models into images, robot navigation, and creating and matching as-built 3D models of construction scenes to planned models. Derek has published dozens of papers and several patents, and his work has been recognized with awards including an ACM Doctoral Dissertation Award honorable mention, CVPR best paper award, Intel Early Career Faculty award, Sloan Fellowship, and PAMI Significant Young Researcher award. Derek has served as organizer for many conferences and workshops, including as Program Chair for CVPR 2019. Derek Hoiem is also co-founder and Chief Scientist of Reconstruct, which visually documents construction sites, matching images to plans and analyzing productivity and risk for delay.
