Research

Most of my research efforts have involved trace level analysis on a variety of sample types.  This work has involved environmental and nutritional samples and some work with physiological sample matrices.  The techniques we have used have include gas and liquid chromatography, atomic absorption spectroscopy, electrochemistry, enzymatic analysis, a little work with radioimmunoassay, and recently some work with gas chromatography/mass spectrometry.

In almost all cases these projects have been pursued with undergraduate collaborators.  At Centre, undergraduate
research can be done either during the school year or during the summer.  During the school year, students can receive academic credit as CHE 40C for one to four credits.  During the summer months student collaborators can be supported either by institutional funds or external grants.

During summer 2004, Josh Abbott, Ben Angel and I developed a method for determination of the widely used herbicide atrazine in surface waters. Atrazine is used primarily in corn production and previous work has shown that improper use can lead to contamination of surface waters. The method uses high resolution gas chromatography and tandem mass spectrometry to provide the selectivity and sensitivity for work at the low levels. The novel contribution of this project is the use of solid phase microextraction for sample preparation. SPME reduces the sample preparation time from several hours to several minutes.

Spring 2005, Julia Covington determined trace levels of lead, zinc, copper, nickel, and cadmium in soil and twig samples taken from a local tree farm where sewage sludge was applied in 1998-99. This is part of a long term study of translocation of heavy metals into woody plants.
