Description of Research Expertise

RESEARCH INTERESTS
Cognitive neuroscience of human working memory and attention.

KEY WORDS:
Cognitive neuroscience, working memory, functional brain imaging, event-related potentials

RESEARCH TECHNIQUES
Functional MRI, event-related potentials (ERPs), behavioral studies in human subjects

RESEARCH SUMMARY
I am interested in elucidating the components of working memory and their corresponding functional neural architecture. More specifically, my research focuses on a venerable question in cognitive psychology: How is information maintained over short intervals in the absence of its immediate accessibility in the environment? In the laboratory, we use several techniques to understand the brain-basis of working memory maintenance (behavioral signal detection measures, event-related potentials (ERPs), and event-related functional MRI) and this reflects my belief that a dynamic interchange must exist between models of cognition and brain-derived data to more completely understand the instantiation of cognitive processes in the brain.
