Research in The Iron Lab
We are finishing up the writing for submission of the work of Jackie Campbell and Lori Schneider on the removal of iron from transferrin. Additional work was carried out after they left, but these additional studies will make this a superb paper. Jackie has now passed her prelims in the Department of Microbiology and Immunology, Vanderbilt University School of Medicine, and is now a Ph.D. candidate. Congradulations to Jackie. Lori has successfully completed two semesters at Iowa State University School of Veterinary Medicine and is thinking about a career in research. This likley means a Ph.D. after her DVM should she decide to go this direction.

I had a good summer studying Advanced Bacterial Genetics at Cold Spring Harbor Laboratory. The course was intense but very good. Research in the lab is centering around the thermodynamics of the transfer of iron from various chelators to bacterial siderophores, and learning more about bioinformatics and molecular modeling. Plans are also being made to get back to isolating and characterizing bacterial iron reductases.

Biography - Click Here

I received my PhD in Geograpy (GIS, remote sensing, and spatial analysis) in 2010, MS in Agronomy (soil chemistry) in 2002, and BS in Agronomy and Genetics in 1991.  Throughout that entire time period, the theme of environmental science has run through my academic work.  After receiving my BS, I served two years in the Peace Corp in Paraguay.
