About

Dr Warren Grigsby is a chemist with specialised experience in synthetic and polymer chemistry. His research focuses on developing chemicals, composites and wood-based materials based on processing biopolymers and renewables. Warren is leading the development of bio-based adhesive and polymer systems that can be used as substitutes for chemicals derived from petroleum.
