Sandra Eaton

Professor and Chair

What I do

My teaching is primarily in undergraduate and graduate physical chemistry. I run a joint research group with Professor Gareth Eaton. We are involved in multiple collaborative research project including EPR instrument development and application to biochemical problems. I am also the Chair of the Department of Chemistry and Biochemistry

Research

The Eaton group develops new electron paramagnetic resonance (EPR) methods and instrumentation to address significant biochemical and chemical problems. A major current emphasis is on EPR methods to improve sensitivity and solve biomedical problems. In collaboration with research groups at the University of Chicago and University of Maryland we are developing methods for imaging local oxygen in vivo and methods for in vivo study of the physiology of tumors. Our team includes chemists, biochemists, physicists, and engineers. Our instrumentation includes state of the art Bruker BioSpin and locally-constructed spectrometers. Dissemination to the research community, in addition to over 350 research papers and reviews, includes a book on EPR imaging, a book on quantitative EPR, and major book chapters about electron spin relaxation and rapid scan EPR.

Key Projects

  • Development of an X-Band Rapid Scan EPR Spectrometer
  • New Nitroxide Spin Labels for Distance Measurements in Biological Systems
  • QLC: EAGER: Toward Magnetic Selectivity with Molecular Clock Qubits
