Geoffrey W. Coates

Tisch University Professor

Olin Chemistry Research Wing, Room 560A

Educational Background

PhD, Stanford University, 1994
BA, Wabash College, 1989



Prof. Coates is the Tisch University Professor in the Department of Chemistry and Chemical Biology at Cornell University. His teaching and research interests involve science at the interface of organic, inorganic, and materials chemistry. The broader impacts of his research include benign polymers and chemical synthesis, the utilization of renewable resources, and materials safe and economical energy storage and conversion.


Polymer synthesis, stereoslective catalysis, mechanism of metal catalyzed reactions


  • Chemistry and Chemical Biology

Graduate Fields

  • Chemistry and Chemical Biology


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.
