Research Interest

The external environment and normal cellular processes can cause damage to DNA. Breaks to both strands of DNA are a significant threat to genome integrity and lead to a complex cellular response comprised of multiple DNA repair pathway options. Defects or inappropriate use of a repair mechanism impacts genome stability, cell survival, organismal development, and disease progression. Despite the consequential decision-making that occurs with each break, how a cell determines the appropriate repair mechanism remains poorly understood. Our laboratory investigates the signaling mechanisms that regulate double-strand DNA break repair to better understand cancer development and to design improved therapeutic approaches.
