Dr. Scott Renneckar investigates the molecular structure and reactions of wood to transform trees and recycled fiber into novel materials that will serve as a platform for the bioeconomy.  Critical to this transformation is the application of fundamental polymer science principles to the characterization, processing, and performance of the biopolymers and biobased composites. His research group’s goal is to apply novel processing methods to create petroleum free composites for the next generation of advanced renewable materials from Canadian forests and fields.
