Research Interests

Past research projects of mine have dealt with turtle population dynamics. I have been involved in south Florida field studies on the interspecific interactions between Brown Anoles (Anolis sagrei) and Green Anoles (Anolis carolinensis); as well as the intraspecific mating interactions among Green Iguanas.

I have also conducted laboratory studies involving Corn Snake's (Pantherophis guttatus) tongue-flick behavior and the behavioral fever of Eastern Ribbon Snakes (Thamnophis sauritus sauritus).

I have cultivated pathogens from the mouths of both Northern Copperheads (Agkistrodon contortrix mokasen) and Southern Copperheads (Agkistrodon contortrix contortrix) in an attempt to emphasize those pathogens and thus reduce the need for administering broad-spectrum antibiotics after Copperhead bites.

My research recently has turned toward environmental microbiology; specifically, bacterial xenobiotic metabolism, groundwater and remediation. I have experience with PAH's, PCB's, VOC's (BTEX, BTEX-ethanol), and organophosphates.

However, I am currently focusing on a comparative study of biogeochemical reductive dechlorination versus enzymatic reductive dechlorination of carbon tetrachloride using augmented and unaugmented soil in a flowing soil column. As well as, monitoring and characterizing the microbial community that exists over the life of the column, with community level physiological profiling and fluorescent in situ hybridization. The goal is to determine if there is a more efficient means of remediation than the current pump and treat method used at the Superfund site located in Hardeman Co. Tennessee, from which my soil sample originate.
