Greg DeAngelis received his Ph.D. in bioengineering from the University of California, Berkeley, in 1992 and completed his postdoctoral research at Stanford University in 1998. Since 2007, he has been a professor in the Departments of Brain & Cognitive Sciences, Biomedical Engineering, and Neurobiology & Anatomy, and the Center for Navigation & Communication Sciences and the Center for Visual Science at the University of Rochester. In 2010, he became the chair of the Department of Brain & Cognitive Sciences at the University of Rochester.
Dr. DeAngelis’ laboratory studies cortical circuits that mediate visual perception and visually guided behavior. This work involves a creative fusion of the disciplines of neurophysiology, psychology and computation. Monkeys are trained to perform demanding discrimination tasks, and single or multiple neurons in their visual cortex are recorded during performance of these tasks. This allows the lab to directly compare the ability of neurons to discriminate between different sensory stimuli with the ability of the behaving animal to make the same discrimination. This approach also allows the lab to examine the relationship between neuronal activity and perceptual decisions (independent of the physical stimulus). In addition, the techniques of electrical microstimulation and/or reversible inactivation are used to establish causal links between physiology and behavior. Computational modeling plays an important role in interpreting results and guiding future experimentation.
