My research focus
primarily focuses on the design and analysis of experiments for quality
improvement. Of exceptional interest to me are the areas of sequential
experimentation and response surface methods. Experiments are regularly
performed by practitioners and researchers in many diverse fields of study with
the common objective of utilizing experimental data to more fully understand
some system, process, organization, etc. under study. Ultimately, my goal is to
develop methodologies/tools for the purposes of model building, process
characterization/optimization, and quality improvement that are user-friendly
and that aid an experimenter in more readily understanding their results.
