Research Interests

Mathematical modeling

Interests include the development of general mathematical approaches to human information processing, cognitive psychology including visual pattern recognition, memory scanning, decision theory, and human factors.

Some specific research topics:

  • Mathematical models and experimentation in pattern (e.g., letter) and face recognition, and visual display and memory search.
  • Mathematical investigations of the testability of issues in information processing, such as parallel vs. serial processing.
  • Human decision making from an approach based on psychologically oriented stochastic process theories.
  • Dynamics and process models in clinical phenomena.
