Work in my laboratory has two related foci: (1) an interdisciplinary exploration of human memory using a broad array of cognitive neuroscience methods to permit identification and characterization of the brain’s various memory systems, and (2) functional neuroimaging studies of a range of cognitive processes in the human brain. The memory work combines neuropsychological studies of patients with memory impairments, eye movement monitoring studies, computational modeling, and functional neuroimaging studies. The neuroimaging work involves the use of fMRI to permit mapping the brain substrates of learning and memory (including especially the hippocampal system), and of attentional and executive functioning in humans.
My lab also collaborates with the laboratory of Professor Arthur Kramer, investigating aging and cognition.
