My main area of research is mathematical models of visual information processing. The aim of this research is to understand the cognitive mechanisms involved in translating perception into action. My theoretical and experimental work investigates perceptual encoding mechanisms, selective attention, decision mechanisms and the relationships among them. It is also concerned to understand how these mechanisms are implemented neurally. I also do research on communication processes in negotiation. This research aims to identify the features of the communication between negotiating parties that promote or impede the attainment of high-quality outcomes. I joined the Psychology Department at the University of Melbourne in 1993. Before then I lectured at the University of Otago in New Zealand, and was a National Research Fellow at the University of Adelaide. I have held visiting appointments at Northwestern University, Purdue University and The University of California, Irvine, in the United States.
