What I do

I teach graduate courses in chemistry and develop new methods of measuring electron spins, with grants in instrument development and preclinical imaging. My work is based on collaborations in engineering, math, physics, chemistry and oncology. I review papers for many ACS and other journals.

Professional Biography

Gareth R. Eaton received his A.B. at Harvard and obtained his Ph.D. at MIT 1972. Since then he has been in the Department of Chemistry (now the Department of Chemistry and Biochemistry) at the University of Denver. He was promoted to Professor in 1980. He served as Dean of Natural Sciences from 1984-1988 and as Vice Provost for Research from 1988-1989. In 1997 he received the John Evans Professorship at the University of Denver. He teaches inorganic chemistry. His research program involves continuous wave, rapid-scan, and pulse EPR applied to the study of relaxation times, spin-spin interaction, metal ions in biological systems, and EPR imaging. He and his wife, Professor Sandra S. Eaton, have jointly authored about 380 research papers and book chapters. In 2002 they jointly received the Bruker prize and in 2008 they became Fellows of the International EPR/ESR Society. He is a Fellow of the Royal Society of Chemistry.

The Eaton group develops instruments, experimental methods, and data analysis tools to characterize unpaired electrons and their application to biomedical problems. Spectrometers have been constructed for continuous wave, pulse, and rapid scan EPR and imaging. Free radicals and metal ions have been studied at multiple frequencies from 250 MHz to 34 GHz. Applications include in vivo imaging, protein structure determination, and studies of materials important for areas as diverse as quantum computing and solar energy. The Denver lab integrates engineering, physics, math, chemistry and biochemistry to accomplish these goals.
