My research investigates the influence of goal-directed attention on memory at both short and long timescales. I am interested in how top-down attentional control processes govern which mental representations are maintained in an active state on a moment-to-moment basis while ensuring that distracting stimuli are appropriately ignored. And I am also interested in how an individual’s goals and associated attentional states serve to guide the formation of a more durable mnemonic record of select experiences or facilitate the retrieval of relevant episodic details from one’s past. To characterize the neural systems subserving human memory and attention, I have developed and applied novel fMRI analysis techniques that exploit the richness of the data. Rather than simply using fMRI to isolate the functional contributions of individual brain regions, my work has also sought to elucidate the role of dynamic interactions between brain regions, as well as to decode the informational content of distributed brain activity patterns.
