    Chair of the Optical Society s Color Technical Group 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 Representative Recent Publications See Publications for more or download Brainard s CV in PDF Format Or visit Brainard s Google Scholar Page Spitschan M Datta R Stern A M Brainard D H Aguirre G K 2016 Human visual cortex responses to rapid cone and melanopsin directed flicker Journal of Neuroscience 36 pp 1471 1482 Download PDF Lindsey D T Brown A M Brainard D H Apicella C A 2015 Hunter gatherer color naming provides new insight into the evolution of color terms Current Biology 25 2441 2446 doi 10 1016 j cub 2015 08 006 Download PDF Press coverage Science World Report Medical Daily Phys org Radonjić A Cottaris N P Brainard D H 2015 Color constancy in a naturalistic goal directed task Journal of Vision 15 13 3 http jov arvojournals org article aspx articleid 2436912 doi 10 1167 15 13 3 Spitschan M Jain S Brainard D H Aguirre G K 2014 Opponent melanopsin and S cone signals in the human pupillary light response PNAS 111
