This expert is internationally recognized for his research on the effects of chemicals and chemical processing on the structural performance of wood and wood-composites. This research has resulted in over two dozen peer-reviewed publications on the effects of preservatives and preservative treatment on the physical and mechanical properties of wood. This research has been resulted in several new design adjustments or process limitations in National Codes and Standards in the US and Canada.
He is also internationally recognized for his research and technological development of the concepts of using engineered biocomposites as a value-added tool to promote and to fund sustainable forest management. He formerly led this emerging approach through his long-work with the International Union of Forest Research Organizations (IUFRO) Division 5 Forest Products. From 2003-2012, he was the vice-chair of the Division 5.05 Composites Research Group of IUFRO in which he focused on enhancing the performance and durability of engineered biocomposites and the long-term sustainability of bio-based composites.
He started his own consulting firm specializing in forensic wood science, wood durability and bioresource sustainability in 2008. He served as Project Leader from 2001 to 2008, of the Engineered Composites Science Research Work Unit. He had primary responsibility for the processing and serviceability of wood-based and wood-plastic composite products. This research group is recognized by the building codes, the wood industry, and standard organizations as having a leadership role in providing unbiased technical information on manufacturing of and serviceability requirements of wood-based and wood-plastic composite products.
The multidisciplinary FRT-Serviceability Team received national recognition by the building codes, the wood industry, and standard organizations for having taken a leadership role in providing unbiased technical information on serviceability assessment of fire-retardant treated plywood roof sheathing. The team also pioneered mechanical- and chemical-based techniques for residual serviceability assessment and predictive models to estimate residual serviceability of wood products in-service. This research resulted in over another two dozen peer-reviewed publications. It has also resulted in four National Standards (ASTM D5516-94, D-5664-95, D-6305-98, and D-6841-02) and major revisions to FR-Treating Standards (AWPA C20 & C27, now AWPA U-1 & T-1).
His work on the very early stages of biological decay showed that changes in the chemical composition of the wood cause significant reductions in wood strength before measurable weight loss occurs. From an engineering perspective, estimating strength loss and residual strength is the critical element in assessing wood serviceability/durability for structures in-service as affected by wood decay. Collaborative studies have shown close a relationship between the degradation of hemicellulose and wood strength losses. Residual strength of degraded wood can be predicted using models developed by this collaborative team. The changes in chemical composition appear to be similar in both the biological and chemical systems. Understanding the relationship between chemical composition and strength loss is critical in developing models to estimate strength loss caused by biological, chemical or thermal agents.
