Sandra Eaton

Eaton completed her bachelor's degree in chemistry at Wellesley College in 1968.{{Cite web|url=http://portfolio.du.edu/seaton|title=DU Portfolio|website=portfolio.du.edu|access-date=2018-03-26}} She was elected to Phi Beta Kappa at Wellesley and published her undergraduate research. She earned a PhD at the Massachusetts Institute of Technology in 1972.

Eaton joined the University of Colorado Denver in 1973 as an assistant professor. She received a National Science Foundation Visiting Professorship for Women in 1984, and joined the University of Denver, where she was appointed professor in 1990.

Eaton is based in the EPR Center at the University of Denver.{{Cite web|url=https://epr-center.du.edu/|title=EPR Center {{!}} Natural Sciences & Mathematics {{!}} University of Denver|last=Denver|first=University of|website=epr-center.du.edu|language=en|access-date=2018-03-26}} Her research is focused on electron paramagnetic resonance, which she uses to study organic radicals and transition metal ions. Using pulsed EPR it is possible to measure electron spin relaxation, which can help uncover the dynamics of molecules. examined the frequency dependence of electron spin relaxation in fluid solution for several important types of radicals.{{Cite journal|last1=Sato|first1=H.|last2=Kathirvelu|first2=V.|last3=Fielding|first3=A.|last4=Blinco|first4=J.

She wrote "EPR Imaging and in Vivo EPR" in 1991.{{Cite book|title=EPR imaging and in vivo EPR|others=Eaton, Gareth R., Eaton, Sandra S., Ohno, Keiichi|date=29 November 2017 |isbn=9781315892788|location=Boca Raton, FL|oclc=1020789984}}
