Emerson/Stokes Research Group

The Emerson/Stokes Research Group (ESRG) comprises a diverse team of scientists who share a keen interest in exploring innovative reactions and processes that intersect the realms of inorganic chemistry, organic chemistry, and biology. The primary focus of research within the ESRG centers on chemical and biochemical systems, primarily emphasizing the chemistry of first-row transition metal ions, with a special emphasis on the pivotal role played by their ligand architecture in governing their chemical behavior. Our approach to investigating these systems encompasses a multifaceted toolkit that draws from the fields of biology, biochemistry, biophysics, organic chemistry, inorganic chemistry, and catalysis. If you are enthusiastic about collaborating with us or becoming a part of our team, please do not hesitate to get in touch!
