Steve Shevell is Professor of Psychology and Ophthalmology & Visual Science, a faculty member in the graduate program in Computational Neuroscience, and the Director of the Institute for Mind and Biology. He received an undergraduate degree in Psychology and an M.S. in Engineering from Stanford University; and an M.A. in Statistics and Ph.D. in Mathematical Psychology from the University of Michigan.

He has served as the founding associate editor of the Journal of Vision, senior editor of Vision Research, editor of the Optical Society of America's most recent edition of The Science of Color, president of the  Vision Sciences Society.

Ryan received his B.S. in Biology and Honors from the University of North Dakota in 2012. In 2015, he received his M.S. in Vision Science from the Ohio State University, working with Dr. Delwin Lindsey and Dr. Angela Brown on color naming and perception.

Ryan is interested in visual perception. In particular, he is interested in the neural mechanisms which mediate color and brightness perception, and how they interact to give us meaningful information about the brightness and color of objects in the environment despite constant changes in lighting.

Jae is excited to be working with Dr. Shevell to explore the nervous system's capacity to render an instantaneous representation of the visual world, resolving the inherent ambiguity and noise. Historically, scientists have studied grouping processes that enhance the similarity among percepts, effectively smoothing over physically present differences. Employing binocular rivalry and probability theory, they are investigating the flip-side perceptual-enhancement process, dissimilarity-enhancement. Enhancing the perceptual dissimilarity among the objects in view may contribute to our ability to act on the world around us.

Sunny is a PhD graduate student working with Dr. Steven Shevell. He received his Bachelor's in Psychology from the University of Hong Kong in 2015 and his Master's in Psychology from the University of Chicago in 2017.

Sunny's interests include visual perception, attention, and the intersection of the two. He is currently investigating whether the ambiguity of the visual information about an object is itself a feature of that object, as color or motion is an object feature.  

Xiaohua Zhuang is an Assistant Professor of Psychology at the Illinois College of Optometry. She is a part-time Research Associate in the Shevell Lab. Xiaohua received her undergraduate degree in Psychology from Peking University in China, and her M.S. in Statistics and Ph.D. in Cognitive Psychology from Rutgers University, NJ.  

Xiaohua studies visual processing of luminance and color, as well as how eye diseases affect these visual processes. She is currently working on projects to investigate the role of the magnocellular visual pathway in processing luminance and color under binocular rivalry and inter-ocular switch rivalry. 

Linda is a programmer working with the Shevell Lab, assisting in the development of programs for experiments using XCode and MatLab. Her specializations include calibrating the luminance and chromaticities presented on color display systems used in experiments.
