Integrated cognitive systems, computational cognitive modeling, cognitive engineering. Interested in basic and applied research that leads to understanding the interplay of cognition, perception, and action in routine interactive behavior.
These interests entail the understanding of top-down vs bottom-up control of behavior, the role of implicit vs explicit knowledge, internal vs external representations, and knowledge in-the-head vs knowledge in-the-world.

"Psychology has arrived at the point of unified theories of cognition--theories that gain their power by positing a single system of mechanisms that operate together to produce the full range of human cognition. I do not say they are here. But they are within reach and we should strive to attain them." Newell, A. (1990). Unified theories of cognition. Cambridge, MA: Harvard University Press.
“There is nothing so useful as a good theory.” Lewin, K. (1951). Field theory in social science. New York: Harper Row.

My research interests can be classifed into topics, domains, or methods. Topics are basic cognitive science issues such as human error, serial attention, cognitive workload, and interactive behavior. In my work on these topics I distinguish between basic versus applied research. When the topic is studied in the context of a simple laboratory experiment the work is basic research. When it is studied in the context of a real-world domain, the work is applied research. Domains that I have studied include the submarine Approach Officers' attempts to locate enemy submarines hiding in deep water, telephone operators, Lisp programmers, usability, and human-computer interaction.Whether it is basic or applied, different topics require the use of different research methods. Methods that I have used include GOMS, ACT-R, ACT-R/PM, action protocol analysis, verbal protocol analysis, and simulated task environments.
Topics, domains, and methods are obviously intertwined. Below I have tried to put together some pointers to parts of my work that are relevant to each. (However, for something that approaches a coherent world-view see my Research Statement.)
