Dr. James E. Coffield


EDUCATION:

Ph.D. Analytical Chemistry, December 1989.  The University of Tennessee, Knoxville, TN.
B.S. Chemistry, June 1983.  The University of the South, Sewanee, TN.

DISSERTATION RESEARCH:

Reduction of Aromatic Compounds in Basic Chloroaluminate Melts: The study of the mechanism and kinetics of the decay of aromatic radical anions in room temperature, chloroaluminate melts.  This included the development of a microprocessor-operated spectroelectrochemical apparatus based on the mutual interfacing of an OMA-3 diode array spectrometer, a PAR Model 273 potentiostat and an inert atmosphere glove box.  Fiber optics were used extensively in this work.

EXPERIENCE:

May 2001 - August 2001
NASA-ASEE Summer Research Fellowship.  Johnson Space Center, Houston, Texas.  Investigation of High Iridium Concentrations in Carboniferous Rock Samples Using Instrumental Neutron Activation Analysis and Inductively Coupled Plasma Mass Spectrometry (NASA Colleague - Dr. Marilyn M. Lindstrom, Astromaterials Research Office).

  • Impact processes played a crucial role in the early evolution of our planet and, though considerably less frequent, are still of great importance today. Understanding the history of impact processes on Earth, in particular their role in the development and evolution of life on Earth, is one of the significant questions confronting mankind at the beginning of the 21st century. Obvious evidence of major impacts, such as visible craters, provide only a slight glimpse at these powerful events. Other indicators of impact events, such as elevated siderophile concentrations, are at times ambiguous and difficult to interpret.  Adding to the understanding of the effectiveness (and limitations) of the use of elevated siderophiles as an indicator of impact events, as well as elucidating other process that can produce similar results, was the goal of this research.
