Silver Award for Professor Keith Earle

Professor Keith Earle (Physics) has been chosen with Dr. Graham Smith (Physics, University of St. Andrews, Scotland) to receive the International EPR Society’s Silver Medal for Instrumentation 2011.  The Silver Medal is awarded for significant contributions to EPR (ESR) Spectroscopy in the areas of Biology/Medicine, Chemistry, Physics/Materials Science, or Instrumentation on a rotating basis.  Dr. Earle and Dr. Smith were given the Silver Award in recognition of their outstanding contributions to the design and implementation of quasi-optical techniques for the instrumentation needs of High Field EPR.

In favorable circumstances, High Field EPR can provide unprecedented resolution of structural details and dynamic modes of, e.g., proteins, DNA, and RNA in solution, which in turn can inform models of function.  Due to performance limitations of the available sources and detectors needed for performing High Field EPR, efficient means of generating and detecting the High Field EPR signal are at a premium.  Quasi-optical methods allow EPR spectroscopists to bridge the gap between the microwave techniques common in conventional (low field) EPR spectrometers and the optical techniques appropriate for infrared observations, for example.  Over the years, Dr. Earle and Dr. Smith have pioneered technical solutions that have addressed the challenges of working in this intermediate region.  Many of these techniques are now standard for performing High Field EPR.  It is this work that has been chosen for recognition by the International EPR (ESR) Society.
The International EPR (ESR) Society was formed in 1989 and maintains a database of over 3,000 scientists who are involved in EPR (electron paramagnetic resonance) research.  The Society is international in scope and covers the entire range of disciplines that use EPR.   The acronym `ESR’ stands for electron spin resonance which is a recognized sub-field of EPR of particular relevance to biophysics and biochemistry.
