My current research interests are in environmental bioanalytical/analytical chemistry. My main projects are in the development of novel biosensors that use synthetic DNA fragments as probes for the detection of environmental contaminants in aquatic systems and the study of cellular DNA damage from environmental agents such as ultraviolet radiation and polycyclic aromatic hydrocarbons.
