Research Description

My research program is primarily focused on problems of experimental design. One design problem of interest in recent years is related to response surface methodology, namely, using second-order polynomials to approximate the relationship between variables in a physical system. Another problem is the development of experimental designs to validate matching processes used in forensic science.One application in which we have been involved focuses on algorithms that match toolmarks found at a crime scene with laboratory samples.

An application of special interest to me is the design of computational experiments, i.e the planning of "runs" of a large computer model and subsequent examination of their outputs to answer specific questions concerning the model. Much of this work involves sensitivity and uncertainty analysis, or the question of how the code can best be "validated" against limited physical data.
