The Project Areas:

Project: The Tools:
  • HPLC system, several columns, fraction collector for separation of biotoxins from cell extract.
  • Bioassay tests to confirm toxicity of HPLC fractions.
  • FTIR for analysis of functional groups in the isolated toxins.
  • Access to NMR, LC-MS/MS for additional structural information on the isolated toxins.
  • GC-MS for separation, identification, and quantitation of low-level environmental contaminants including phthalates and brominated diphenyl ethers.

Status: (as of 9/2010)
    I started in the fall of 2007 as a new faculty member at UW-Oshkosh after nine years at The Citadel in Charleston, SC.  I completed an environmental project assessing the sediments that have built up in stormwater retention ponds in coastal SC.  This project was funded by SC Sea Grant.  I am continuing my efforst to isolate polar toxins produced by Trichodesmium thiebautii.  The trichodesmium project has resulted in a presentation at a regional ACS meeting (Fall 2006) and a presentation by a research student (Bydairk) at the Pittcon national meeting in the spring of 2007.  Other recent projects include analysis of bile acids by LC-UV, demonstration of the formation of biogas by decomposition of Cladophora algae, and investigations of the effects of silver nanoparticles on bacterial populations.  The Polymer Photochemistry project resulted in a presentation (Crawford) at the Southeast Regional ACS meeting in Fall of 1999.  Two students (Philpott, Browning) participated in the Marine Biotoxins work during the 2000-2001 school year, resulting in two undergraduate theses.  One student (Ellisor) spent the summer of 2002 working on isolating maitotoxin from Gambierdiscus toxicus and continued this work for his senior thesis.  He presented his work at the Southeast Regional Meeting of the American Chemical Society (SERMACS) in November 2002 and at the Pittcon Analytical Chemistry Conference in Orlando in March of 2003.  Another student (Llhamlak) continued the G. toxicus work as a summer and senior thesis project during the 2004-2005 school year.  The Plant Pigment Photochemistry project has been funded by the Citadel Foundation for three years, and several undergraduate students (Philpott, Browning, Nickles, Williams, Caldwell, Ybarra) have participated in this project during the summer and school year, resulting in presentation at local and regional meetings.  Brian Williams spent the 2003-2004 school year quantitating the ability of protein skimmers to remove metal ions from saltwater. This work resulted in a publication in the Journal of Undergraduate Chemistry Research.
