Curriculum Vitae
Research Program:
This research is focused on better understanding the neural systems mediating human learning, memory, and emotion. Behavioral and functional MRI studies from this laboratory investigate the acquisition, expression, and extinction of human Pavlovian fear conditioning. We are interested in the role of awareness in the expression of fear-related behaviors, the neural circuitry mediating aware and unaware fear memory processes, and brain regions that process properties of fearful stimuli compared to regions that produce behavioral and autonomic fear responses.
