Interest Areas

Dr. Morris's research is primarily focused on problems of experimental design, especially for studies involving computational models. Recent applications involve experimental design for response surface problems characterized by known symmetries among experimental factors, and experiments for evaluating and validating matching processes used in forensic science. The design and analysis of computer experiments (DACE), involves the planning/selection of "runs” of a large computer model and subsequent examination of the resulting output to validate, calibrate, or develop relatively fast- running approximations of the model.
