Thesis title: Fenton and Fenton-like reactions - the nature of oxidizing intermediates

Research Interests:

- Food Science - Evaluation of the various analytical techniques used in the quantization of total and molecular levels of antioxidants in various foods such as fruits and vegetables. How storage, regional cultivation and preservation affect the levels and distribution of these antioxidants.

- Environmental - Investigation of the levels of heavy metals such as arsenic, lead and chromium in the, sediments, soils, composts and waters in North east Alabama. Special emphasis on the speciation and possible transformation of these pollutants in the various matrices.

- Free radical Research - Fenton chemistry; an investigation to the mechanism involved in the oxidation of metals by peroxides in Fenton and Fenton-like reactions.

- Phytoremediation - The uptake of heavy metals by various plants such as Kudzu with a look at both the physiological and toxicological effects.
