Current Research

Botanical wood anatomy

  • Evolution of wood anatomical diversity
  • Wood anatomical flood response to seasonal inundation
  • Characterization of wood phenotype, including figure, in naturally occurring tree mutants (Populus, Prunus, Acer)
Forensic wood science
  • Machine-vision wood identification with the XyloTron
    • Commercial woods of Mozambique
    • CITES-woods
    • Dalbergia and Pterocarpus
    • North American hardwoods
    • Commercial woods of Ghana
    • Commercial woods of Colombia
    • Commercial woods of Peru
  • Further develop organellar microcapture for trace evidence
Biocentric wood science
  • The effect of scale on wood electrical properties and moisture relations from the ultrastructural to the growth ring level
  • Practical methods to determine dimensional change coefficients for the flooring industry
Other interdisciplinary cooperations or projects
  • Product claim verification in forest products supply chains and improved monitoring and determination of best practices
  • Identification and dating of the wooden cultural patrimony of the Taino people

Research Interests

  • Elucidate the evolutionary interplay between ecology and phylogeny in wood anatomy as determinants of structure-function of trees, shrubs, and lianas.
  • Conduct foundational research and develop tools and methods to improve the ability of the wood industry to comply with - and law enforcement to apply - laws governing illegal logging.
  • Improve the use and utility of wood as a material by researching the biological origins of fundamental wood properties at the mesoscale and how they influence wood behavior in a range of contexts.

Past Research

  • Systematic wood anatomy
  • Traditional wood identification
  • Anatomical aspects of early wood colonization by wood decay fungi
  • Wood-finish and wood-adhesive interactions

Why This Research is Important

Wood is a fundamental part of human material culture going back to prehistory.  We have used it for tools, for fuel, for shelter, and even (a surprise to many) for food.  Understanding the biological origins of wood provides a critical contextual framework for interpreting wood evolution, wood forensics, and the modern use of wood in its many forms.
