Research Interests:
DNA damage and repair, particularly mitochondrial DNA and how these processes play roles in the etiologies of diabetes, neurodegenerative diseases, cancer, and the normal process of aging. We utilize molecular biology technology study the damage and repair in specific sequences of both nuclear and mitochondrial DNA. Our particular interests lie in understanding how specific lesions are repaired and factors that may prevent this repair and cause disease processes.
