Duje Tadin is the 2014 winner of the Elsevier/VSS Young Investigator Award. Trained at Vanderbilt, Duje Tadin was awarded the PhD. in Psychology in 2004 under the supervision of Joe Lappin. After 3 years of post-doctoral work in Randolph Blake’s lab, he took up a position at the University of Rochester, where he is currently an associate professor. Duje’s broad research goal is to elucidate neural mechanisms that lead to human visual experience. He seeks converging experimental evidence from a range of methods, including human psychophysics, computational modeling, transcranial magnetic stimulation (TMS), neuroimaging, research on special populations, collaborations on primate neurophysiology, and adaptive optics to control retinal images. Duje is probably best known for his elegant and illuminating research on spatial mechanisms of visual motion perception – work that has had a lasting impact on the field. He developed a new method to quantify motion perception using brief, ecologically relevant time scales, and then used it to discover a functionally important phenomenon of spatial suppression: larger motion patterns are paradoxically more difficult to see. Duje’s results revealed joint influences of spatial integration and segmentation mechanisms, showing that the balance between these two competing mechanisms is not fixed but varies with visibility, with spatial summation giving way to spatial suppression as visibility increases. He has also made significant contributions to several high-profile papers dealing with binocular rivalry, rapid visual adaptation, multi-sensory interactions, and visual function in individuals with low-vision and children with autism.
