Biography

David H. Brainard is the RRL Professor of Psychology at the University of Pennsylvania.  He received an AB in Physics (Magna Cum Laude) from Harvard University (1982) and an MS (Electrical Engineering) and PhD (Psychology) from Stanford University in 1989.  He is currently the RRL Professor of Psychology at the University of Pennsylvania and his research focuses on color vision and color image processing.  He is a fellow of the Optical Society, ARVO and the Association for Psychological Science.  At present, he directs Penn's Vision Research Center, co-directs Penn's Computational Neuroscience Initiative, co-directs Penn's NSF funded certificate program in Complex Scene Perception, is on the Board of the Vision Sciences Society, and is a member of the editorial board of the Journal of Vision.  

Research Interests

The Brainard Lab studies human vision, both experimentally and through computational modeling of visual processing. Our primary concern is with how the visual system estimates object properties from the information available in the light signal incident at the eye. To study this general problem, we conduct psychophysical experiments to investigate questions such as how object color appearance is related to object surface properties under a wide range of illumination conditions and how color is used to identify objects, and formulate computational models of the results. In addition, we are interested in developing machine visual systems that can mimic human performance and in understanding the neural mechanisms of vision.
