Sergei is a scientist at Systems Neurobiology Laboratories at the Salk Institute for Biological Studies in La Jolla, California, where he founded the Collaboratory for Adaptive Sensory Technologies. Trained in Neurobiology (Weizmann Institute of Science), Experimental and Cognitive Psychology (University of Virginia), and Vision Science (University of California at Berkeley), Sergei is interested in foundations of perception and computational neuroscience. Much of his research dwells on the interface between two aspects of vision: the entry process called early vision and the constructive process called perceptual organization. Sergei studies the principles of neural computation underlying these processes, in particular how visual systems organize information for perception of motion and change. He also studies sensorimotor integration, asking how vision and haptics are used to guide action – in view of the dynamic nature of the environment, its varying uncertainties and risks. As a founding member of the 5D Institute, Sergei is increasingly involved in studies and design of immersive and built environments.
