Greg Appelbaum is an Associate Professor in the Department of Psychiatry and Behavioral Sciences in the Duke University School of Medicine. He is a member of the Brain Stimulation Division of Psychiatry, where he directs the https://psychiatry.duke.edu/optilab" title="Opti Lab">Human Performance Optimization lab (Opti Lab) and the https://psychiatry.duke.edu/brain-stimulation-service-center" title="BSSC">Brain Stimulation Research Center   As a member of the Duke Institute for Brain Sciences he teaches and advises in the Neuroscience major, is an affiliate of the Center for Cognitive Neuroscience, and has a secondary appointment in the Department of Psychology and Neuroscience. 

Dr. Appelbaum's research interests primarily concern the brain mechanisms underlying visual cognition, how these capabilities differ among individuals, and how they can be improved through behavioral, neurofeedback, and neuromodulation interventions. Within the field of cognitive neuroscience, his research has addressed visual perception, sensorimotor function, executive function, decision-making, and learning/expertise. In this research, he has utilized a combination of behavioral psychophysics coupled with the neuroscience techniques of electroencephalography (EEG), transcranial magnetic stimulation (TMS), functional magnetic resonance imaging (fMRI), and functional near infrared spectroscopy (fNIRS).
