Douglas J. Gardner is Professor and Program Leader of Sustainable Materials Technology in the School of Forest Resources at the University of Maine. He is also member of the Advanced Structures and Composites Center and Forest Bioproducts Research Institute. Gardner’s research and teaching focus on polymer and interfacial science aspects of wood-polymer composite materials. He has been involved in research ranging from adhesion, surface science, cellulose nanocomposites, to extruded wood plastic composites, and additive manufacturing. At the Composite Center they have recently presented the world’s first 3D printed fully bio-based home. Prof. Gardner reviews his career path, how much SWST has helped him to build a strong network, and reveals also what he enjoys in addition to being a professor and researcher: singing and playing the guitar.
