Sergei Gepshtein, M.SC., Ph.D.

Bio-Sketch

Sergei is a scientist working in the areas of perceptual psychology and sensory neuroscience. He is a member of the Center for Neurobiology of Vision at the Salk Institute for Biological Studies in La Jolla, California, where he studies boundaries of perception in the natural world and in visual media. He directs the Collaboratory for Adaptive Sensory Technologies, which he founded at the Salk Institute with the goal to translate results of basic sensory research toward a wide range of applications: from immersive visual technologies and adaptive sighting devices to architecture, urban design, and forensic science.

Before joining the Salk Institute, Sergei investigated stereoscopic vision and interaction of vision and haptic sense at the University of California, Berkeley. then he studied computational principles of perceptual organization and pattern visibility at RIKEN Brain Science Institute in Japan.

His research received grants and awards from the Swartz Foundation for Computational Neuroscience Research (USA), the National Institutes of Natural Sciences (Japan), the National Science Foundation (USA), and the National Institutes of Health (USA).

Sergei increasingly takes part in research of built environments and design of immersive media: as a founding member of the USC World Building Institute, as an inaugural recipient of the Harold Hay Research Award from the Academy of Neuroscience for Architecture (ANFA), and as a member of Freeman Design Leadership Council. He recently joined the Board of Directors of ANFA, to further our understanding of human response to built environments. He also helps to develop the educational curriculum at the emerging juncture of neuroscience and architecture, pioneered by NewSchool for Architecture & Design in San Diego.

Sergei has recently teamed up with the narrative designer Alex McDowell, RDI, to establish the Center for Spatial Perception & Concrete Experience (SPaCE) at the University of Southern California in Los Angeles. SPaCE develops new forms of physical, immersive, and environmental media, focusing on experience of space as a sequential, narrative process.
