for his path-breaking contribution to the development of instrumentation and accompanying software for the characterization of the structure and quality of wood, one of the world’s most complex composite materials. He developed a practical means to quickly characterize the important qualities of the component fibers of a large number of tree samples such that wood can be directed and used to its most valuable end use, whether that use be as solid wood or as pulp for the total range of different paper and packaging products. The SilviScan system integrates fiber and density measurement functions including x-ray densitometry, x-ray diffraction and tomography in a single instrument permitting extremely rapid and efficient assessment of wood properties for applications to silviculture, forest genetics and tree breeding, and to forest resource evaluation.
