About

My early research examined neural mechanisms of sensory-based recollections. I have also become interested in understanding how memory operates under varying demands on attention, and how we arrive at decisions that are based on our memories and perceptions. The lab has been studying perceptual decision making in order to identify neural signals related to different stages of the decision process. We have recently been building from our early research in this area to study how memory, attention, and decision-making abilities change in healthy aging. We use psychophysical, modeling, and brain imaging approaches to study these topics. Recently, our research has been funded by the Alzheimer’s Association, the National Institute of Mental Health, and the National Science Foundation.
