Research Interests:

My research is concerned with the perceptual and cognitive processes underlying complex behavior. The basic research problems I am working on include visual space perception, visual control of locomotion, and spatial cognition, including navigation. Much of my work involves virtual environment technology, a tool that greatly expands the possibilities for experimental research. On the applied side, I have been director of a project developing a navigation system for blind people

Information for prospective students and postdocs:

I have retired from teaching and am not accepting new students but may wish to sponsor interested postdocs.
