Dr. Fitzpatrick was named Scientific Director and Chief Executive Officer of the Max Planck Florida Institute for Neuroscience on January 3, 2011. Prior to his arrival in Jupiter, Dr. Fitzpatrick was the James B. Duke Professor of Neurobiology at the Duke University School of Medicine, Durham, NC and Founding Director of the Duke Institute for Brain Sciences.
Dr. Fitzpatrick’s scientific contributions have earned him international recognition as a leader in systems neuroscience, with a focus on the functional organization and development of neural circuits in the cerebral cortex—the largest and most complex area of the brain, whose functions include sensory perception, motor control, and cognition. His research has played a pivotal role in defining the modular architecture of cortical circuits and using this architecture as a functional referent to explore rules of intracortical connectivity, address questions of population coding, and probe the role of experience in the maturation of cortical response properties. Current research underway in Dr. Fitzpatrick’s lab utilizes state-of-the-art optical imaging techniques to probe the functional architecture of circuits in primary visual cortex and the critical role that visual experience plays in the proper maturation of these circuits.
Dr. Fitzpatrick has received a number of awards for his research accomplishments, including an Alfred P. Sloan Research Award, The Cajal Club Cortical Discoverer Award, and The McKnight Neuroscience Investigator Award. He has served on numerous scientific advisory boards including the Searle Scholars Program, the DFG (German Research Foundation), the Riken Brain Science Institute, the Max Planck Institute for Neurobiology, and the National Institutes of Health. He has served in an editorial capacity for a number of scientific journals most recently as a Senior Editor for the Journal of Neuroscience. In addition to his scientific achievements, Dr. Fitzpatrick has been recognized for his administrative leadership as the Founding Director of the Duke Institute for Brain Sciences. In this capacity, he led the development of numerous cross-school, interdisciplinary initiatives that spawned new areas of collaborative research, recruited new faculty, and supported the development of new educational programs in the neurosciences.
