My current research interests are in human cognitive processes—such as perception and motion; memory and learning; and problem solving—and in models based on them. I am also interested in their application to artificial intelligence, human interface, ergonomics, and rehabilitation engineering. I have conducted a number of research projects with rehabilitation therapists. I have also investigated human cognitive processes using several experimental tasks, such as visual illusions, body weight shifting, button pressing, manual tracking, maze searching, a solitaire game, and musical performance. I have been conducting psychological experiments, analyzing the data, and building computational models.
