My research in the Cognitive Science Laboratory looks at the psycholinguistics of language production. Our ability to rapidly and effortlessly transform thoughts into a sequence of meaningful sounds is a remarkable feat, given the incredible complexity of this task.

My lab studies the cognitive processes and architectures that underlie this ability. Of particular interest are cases in which speech goes somehow awry - either in normal speech errors, (slips of the tongue) made on occasion by all speakers (and that can also be experimentally elicited in the laboratory), or in more severe cases of pathological language, such as stuttering. By looking at cases in which language production has gone wrong, we hope to understand how the system works normally.

M.B.B.S. (University of Queensland, Australia)

Ph.D. (University of Illinois)

My research program combines behavioural and electrophysiological methods to investigate the functional and neurological framework underlying central information processing and cognitive control in humans. My research focuses on three interrelated issues: central processing limitations in multiple task performance; executive control in working memory; and examining component processes involved in task switching.

I am also involved with several secondary lines of research, where extensions of my primary work in divided attention and cognitive control are being usefully applied to questions in other areas, including visual perception, language production and medical reasoning and decision making.

I'm interested in which cognitive and perceptual factors influence our assumptions about shared knowledge in written and spoken communication.

I'm interested in the interaction between unconscious and conscious cognitive processes, for example how these interactions play out in learning and generalizing knowledge, particularly in the domain of medicine.
