    Dr. Zunino’s lab is interested in the regulation of genomic stability, gene transcription, and protein translation in immune cells in response to phytochemicals and their metabolites. Dr. Zunino is particularly interested in the epigenetic regulation of genome stability in response to genotoxic and oxidative stress, and the role that phytochemical antioxidants may play in controlling these responses, thus preventing the development of hematological malignancies. Other areas of interest include anti-inflammatory activities of phytochemicals and prevention of autoimmunity.
