B.A. 1983, Ripon College (elected to Phi Beta Kappa, 1983).
Ph.D. 1987, University of Wisconsin-Madison.
Postdoctoral Fellow 1987-89, University of Cincinnati.
Professor Sharpe is interested in the development of environmental chemical
sensors based on fluorescent, powdered, semiconductor materials. He and his
students have found that these materials indicate the presence of pollutants such
as sulfur dioxide (precursor of acid rain) by the decrease in the fluorescent intensity
of the semiconducting materials. Another area of interest is the use of Extended
X-ray Absorption Fine Structure, EXAFS, spectroscopy to study ion
conductivity in polymers.
