Interests:
Trace Analysis: Environmental, Archaeological, and Forensic Applications. The development of sensitive analytical methods has helped provide more detailed information about the small chemical differences between materials which seem similar but have different histories. In some cases, like geological samples, the large scale geochemical processes can give rise to subtle yet understandable differences in those elements which are present at trace levels. We have used instrumental neutron activation analysis and X-ray fluorescence to study several types of geological materials. These materials have been investigated as part of an ongoing effort to interpret the migration of trace elements during geochemical processes. In some cases, these same geological materials have been used by prehistoric humans and hence our studies have had archaeological implications.
