I study the neural processes involved in higher-level cognition, including executive functioning and episodic memory. Specifically, my research has examined (1) the neural processes supporting executive functions, (2) the neural processes supporting episodic retrieval, and (3) how neural processes interact for top-down control of episodic retrieval. My research has addressed these topics through behavioral and neuroimaging (electroencephalography (EEG), event-related potential (ERP), and functional magnetic resonance imaging (fMRI)) methods. This research has shown how multiple brain systems process information and interact to perform rich cognitive abilities.
