My research is currently focused on a variety of geochemical applications especially those pertaining to the relationships among organic matter and other earth processes. I am in the process of concluding research examining the relationships among dissolved and particulate organic matter in zero-order forested watersheds in Mississippi and using organic matter as a proxy for sediment sources and transport. I am also conducting exploratory methods research examining the utility of soil volatile organic compounds (VOCs) as a means to differentiate among the processes associated with soil respiration and CO2 efflux.

My teaching philosophy is based on active, hands on learning. Whether in a formal classroom setting or in an analytical laboratory, my primary goal is to help students become comfortable with instrumentation and their ability to use it effectively. I teach students how to utilize technologies such as ion chromatography, inductively coupled plasma optical emission spectrometry (ICP-OES), dry combustion elemental analysis, and traditional wet chemistry. I have trained dozens of students in the basics of instrumentation and analysis, how to research methods to suit their analytical needs, how to develop Standard Operating Procedures (SOPs), how to troubleshoot effectively, and how to develop and utilize Quality Assurance/Quality Control (QA/QC) procedures to ensure precision and accuracy of results. I prefer to teach students how to take ownership of their instruments and data in order to enable them to better understand the utility and reliability of their data.
