Dr. Caitlyn Clarkson is a staff scientist in Manufacturing Science at ORNL's Manufacturing Demonstration Facility. Dr. Clarkson has a PhD in Materials Engineering from Purdue University and specialized in polymers and polymer composites. She was a National Research Council Fellow at the Air Force Research Laboratories as well as a National Science Foundation IGERT Fellow in the USA. At Oak Ridge National Laboratory, Dr. Clarkson's research 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: recycled and bio-based materials and novel supply chain development; material extrusion manufacturing; self-assembly of small molecules and block copolymers; nanomaterials; reactive extrusion; and crystallization of polymers.
