Inorganic/Materials Chemistry/Organic/Organometallic/Polymer Chemistry

The Coates Group studies the development of new catalysts that can be used for the synthesis of small molecules and polymers. Projects in the Coates Group are interdisciplinary, addressing problems at the interface of organic, inorganic, organometallic, and polymer chemistry. Research The research focus of my group is the development of new synthetic strategies for producing polymers of defined structure. The control of polymer composition, architecture, stereochemistry, and molecular weight allows the indirect control of polymer properties via polymer morphology. Our research projects are interdisciplinary, addressing problems at the interface of organic, inorganic, organometallic, and polymer chemistry.
