Research Interests
The bulk of my research has centered on various issues pertaining to cognitive aging, especially age differences in the variability of cognitive performance. More specifically, I have examined age-differences in the moment-to-moment inconsistency in performance on tasks of speeded decision making, visual search, and working memory. My current research into the matter examines whether individual and age differences in fluctuations of executive control can account for levels of prospective memory performance.

I have also recently become interested in behavioral economics, especially in the context of aging. Specifically, I have been working with several colleagues on studies exploring the roles of age differences in working memory and speed of decision making in risky and impulsive choices.
