Interdisciplinary, cognitive neuroscience study of human learning and memory, with a focus on identifying and characterizing the brain's multiple memory systems. Particular emphasis is on study of the hippocampal (or medial temporal lobe ) memory system, through the study of the memory impairments seen in patients with amnesia. Empirical work combines cognitive neuropsychological, eye movement, fMRI, and ERP studies of various memory performances in normal and neuropsychological populations, together with computational modeling of memory. The overall goal of this research is to better understand the componential organization of memory, and to make progress in mapping the functional architecture of memory onto its neurobiological substrates.
