I am interested primarily in igneous petrology, especially volcanic
phenomena, and also metamorphic petrology and earth-surface aqueous
geochemistry. My research is located in central Arizona and involves a
series of sills which I have called the Central Arizona Sill Complex.
My duties involve the operation and maintenance of analytical
equipment, including a Siemens SRS 300 X-ray fluorescence spectrometer, a
Beckmann Spectraspan V DC plasma spectrophotometer, and a Dionex DX-500
high-pressure liquid chromatograph, as well as the support facilities
used in sample preparation, data processing, and the like. I am a system
operator on our unix-based local area network. Graduate and advanced
undergraduate students come to me for individual instruction in the use
of our laboratory and computer facilities, and in the development of
analytical programs suitable for their projects.
