Research interests

My research focuses on understanding the mechanisms by which exposures to endogenous and/or exogenous toxicants lead to pathology and disease. In particular, I am interested in understanding how defective repair of DNA damage can affect health, with implications to human degenerative diseases associated with aging such as cancer and neuronal degeneration.
