Current Research

The purpose of the research efforts is to enhance the integrity and efficiency of the Forest Products Laboratory through the use, development, evaluation, and promotion of modern statistical methods.


Research Interest

  • Establishment of new and more accurate sampling procedures; cheaper, more efficient testing procedures for evaluating the mechanical properties of structural lumber; and new databases of lumber property information
  • Evaluation and modeling of the effects of environmental factors on lumber properties
  • Development of new statistical analysis procedures
  • Research on the Weibull distribution
  • Research on how to monitor for changes in lumber properties over time
  • Research on uses of small-diameter material
  • Collaborative research with other scientists at FPL as a part of a research team
