Research Interests

My academic and technical background in low-temperature geochemistry forms the foundation for my specialization in stable isotope and trace/minor elemental analytical chemistry. I manage the USF Paleoclimatology, Paleoceanography and Biogeochemistry Laboratory under the direction of Drs. David Hollander and Benjamin Flower.

Currently, the lab houses two Thermo Delta+XL stable isotope ratio mass spectrometers capable of measuring dD, d13C, d15N and d18O in a variety of inorganic and organic sample types. IRMS peripherals include:

- Thermo Kiel-III Carbonate device
- Carlo-Erba NA2500-II EA w/ Costech Zero-Bank aoutosampler
- Thermo TC/EA with modified flow-path,
- Thermo GasBench-II
- Agilent 6890 w/ custom-built GC/TC and GC/C furnaces

I also manage the Hollander-Van Vleet-Fries GC/LC-MS facilty comprised of a Varian 3800/310-MS GC/MS and a Varian 310-MS LC/MS in addition to multiple GC's. I provide analytical consultation/direction to the Byrne-Peebles collaborative LA-ICP-MS lab.

In addition to managing the operation and maintenance of the lab instrumentation and coordinating the development of new methods and approaches to geochemical problems, I maintain the laboratory computer systems (Mac, PC and Linux), participate in field-based research, and maintain the PPB website.
