I am a Professor of Psychological and Brain Sciences at the University of Iowa. The main focus
of my research has been to learn how people match external stimuli with internal states to choose responses and engage in flexible, goal-directed behaviors. I have approached this problem using a range of methodologies and behavioral phenomena, including dual-task interference, bimanual coordination, and cognitive control. Although this work represents a diverse set of findings, a central theme is that response selection processes are not generic but instead depend on the specifics of the task and the context in which it is embedded.
