Current Research

Botanical wood anatomy

  • Evolution of wood anatomical diversity in Croton
  • Wood anatomical flood response to seasonal inundation
  • Characterization of wood phenotype in naturally occurring tree mutants (Populus, Prunus, Acer)
  • Cambial activity of cerrado species in relation to climate and ecology
  • Micromechanical investigation of pit membranes in conifers
Forensic wood science
  • Machine-vision wood identification (with John Hermanson, FPL)
  • Standardize macroscopic imaging of wood
  • Enhanced quantitation of traditional wood anatomical techniques (AcerSwietenia)
  • Anatomically informed DNA optimization of DNA extraction from wood
  • Further develop organellar microcapture for trace evidence
  • Develop bulk DNA extraction protocols applicable to a range of wood products
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
  • Isolation and quantification of tree-ring nitrogen
  • Climate reconstruction of the Younger Dryas period
  • 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
