Cait M Clarkson

Associate R&D Staff Scientist

Dr. Caitlyn Clarkson is an associate staff scientist in the Sustainable Manufacturing Technologies Group at ORNL's Manufacturing Demonstration Facility. In the SMT Group, she supports the biomaterial development program under the SM2ART Collaborative Partnership (formerly known as the Hub&Spoke) between the University of Maine and Oak Ridge National Laboratory and the Circular Economy Portfolio led by Dr. Matthew Korey and Dr. Peter Wang.

Her research at ORNL comprises the development of sustainable material feedstocks and the integration of these materials into advanced manufacturing processes. Her research in bio-based materials is in the development of natural fiber-reinforced composites and hybrid composites, as well as the formulation of bio-based composite feedstock for the material extrusion process known as large-format additive manufacturing (LFAM). Dr. Clarkson's research is also working on the development of circular economies for unwanted, high-volume waste streams: post-consumer recycling (PCR) and automotive shredder residue (ASR). Her work supports the creation of composite feedstocks for applications in LFAM, automotive, and more. Her expertise is in polymeric material development and characterization techniques.

Her research interests include: use of recycled and bio-based materials and novel supply chain development; material extrusion processes like LFAM or direct ink writing (DIW); self-assembly of small molecules and block copolymers; nanomaterials; reactive extrusion; compatibilization; hybrid composites; crystallization and crystallization kinetics in thermoplastic polymers.
