In the blink of an eye—less than half a second—dynamic neuronal networks in our brains process, maintain, and act upon an abundance of information. In my research I seek to construct an understanding, from a network perspective, of cognition built upon first principles of neurophysiology and computational models. To do this I incorporate a variety of methods and tools in my research, including intracranial electrophysiological recordings from humans, scalp electroencephalography from healthy younger and older adults, behavioral and neuroimaging studies involving patients with focal brain lesions, data-mining of large-scale databases, and brain-computer interfacing. Specifically my research program aims to answer three questions: 1) What role does the prefrontal cortex play in shaping and coordinating network activity during complex cognition and executive functioning? 2) Under what circumstances is this network altered or disrupted and what are the consequences of such disruption? And, 3) What are the principles that allow for network communication in noisy internal and external environments? My research addresses these questions across multiple scales ranging from basic neurophysiology to population-wide analyses of cognitive data collected from more than 400,000 participants. My goal is to take cognitive science outside of the laboratory and "into the wild" using distributed data collection and large-scale data analysis to help bridge psychology and basic physiology.
