Dr. Ellison's most active research is in the general field of biomimetics: the study of natural systems for inspiration in new materials development. His current research in this field considers the fibers produced by spiders as the preeminent model of an advanced material produced by a sustainable method. With colleagues in many other disciplines at Clemson University, ranging from molecular biology and bio-chemical engineering to mathematics and physics, he has established a large and highly trans-disciplinary research program in Biomimetic Advanced Materials. This is a national and international research program: Dr. Ellison and others in this group actively collaborate with colleagues at other Universities in the US and abroad. Elements of this program include molecular biology for gene engineering and expression; isolation, purification and material production from the resultant synthetic protein polymers; optimization of the bio-chemical engineering for protein production; characterization of natural and synthetic protein materials; and, mathematical modeling of the biomimetic materials and processes. As part of his interest in bio-based (protein) materials, Dr. Ellison’s studies include natural fibers, most notably wool.
He maintains a secondary collaborative research program in synthetic fiber structure development and process/structure/property relationships. For the study of structure development during melt extrusion of synthetic fibers, he established laboratories in the Center for Advanced Engineering Fibers and Films (CAEFF) for on-line simultaneous WAXD and SAXS and Raman spectroscopy. These laboratories, further developed by other faculty, also house facilities for other process and material parameter measurements. His physical property laboratories house equipment he has developed for mechanical property testing of fibers in tensile and non-tensile loading modes, including a computer-controlled torsion balance, with in-situ Raman spectroscopy capability. His work in the electrical properties of polymers involves primarily dielectric properties and contact electrification through thermally stimulated current studies.
