John D. Medaglia

Dr. Medaglia is a Assistant Professor in the Department of Psychology at Drexel University and Adjunct Assistant Professor of Neurology at the Perelman School of Medicine at the University of Pennsylvania. He graduated from the Pennsylvania State University in 2014, where he studied the effects of traumatic brain injury on cognition and network reconfigurations. He completed his doctoral internship at the Medical University of South Carolina and joined a T32 postdoctoral training program at Moss Rehabiliation Research Institute with mentors Danielle Bassett, Sharon Thompson-Schill, and Roy Hamilton to receive training in network science, cognitive control function, and brain stimulation. Dr. Medaglia is interested in network reconfigurations underlying the maintenance and transitions among cognitive functions, especially in the context of cognitive control. In particular, a major focus of his research is the use of network techniques to inform practical personalized approaches to leverage brain stimulation in experimental and clinical paradigms.
