Dr. Jakes leads a multidisciplinary team with the mission to rigorously employ materials science principles in the study of wood cell walls with an emphasis on mechanical behavior, moisture sorption, and diffusion. Materials science encompasses the study of structure-property-processing-performance relationships. Current wood utilization efforts are hindered by the incomplete identification and understandings of these relationships. Tools to study structure and properties at these small length scales are lacking. This research has required the development of advanced material characterization techniques to probe structures and properties at micrometer length scales and below in wood and forest products. Dr. Jakes leads the FPL Nanoindentation Lab to accurately measure physically meaningful mechanical properties of materials at the micron-scale with an emphasis on wood cell walls. Advanced synchrotron X-ray and neutron techniques have also been identified and adapted to study the structure and properties of forest products at length-scales at and below the cellular level. The combination of these advanced materials characterization techniques have led to multiple new discoveries, including elucidating the roles of lignin and hemicelluloses in wood cell wall micromechanics, identifying nanoscale mechanisms responsible for moisture durability in wood-adhesive bondlines, and identifying diffusion mechanisms through wood cell walls.

Wood is not only the sustainable raw material of choice for our future materials, chemicals, and fuels needs, but increasing wood value and utilization is also critical to maintaining healthy forests and offsetting costly forest restoration efforts. However, advanced materials research is needed for wood to reach its full potential. Dr. Jakes conducts research to accelerate the development of new and improved forest products and other wood-based materials. Throughout the world, a tremendous amount of effort is exerted to improve current forest products and make new forest products with improved properties for new applications. However, current research largely relies on slow and inefficient trial-and-error approaches because the fundamental structure-property-processing-performance relationships are not understood. The improved understanding of these relationships will provide researchers with new and more efficient research directions.
