James Hays is as an associate professor in the School of Interactive Computing, Georgia Institute of Technology. He was recently the Manning Assistant Professor of Computer Science at Brown University. His research interests span computer graphics, computer vision, and computational photography. His recent research includes experiments with crowdsourced sketching that have revealed shared, iconic representations of objects that can be recognized by both humans and machines, as well as the development of a new application that enables users to change a suite of transient attributes of outdoor photos, making photo editing easy for people who might not be familiar with photo editing software. Before joining Brown, Hays worked with Antonio Torralba as a postdoctoral associate at Massachusetts Institute of Technology. He received a Ph.D. in Computer Science from Carnegie Mellon University in 2009 while working with Alexei Efros. Hays is funded by a Sloan fellowship, an NSF CAREER Award and gifts from Microsoft, Adobe, Pixar, and Google.
