DNA damage arising from exposure to environmental toxins and cellular metabolites thwarts DNA replication and leads to genome instability, cell death, and diseases including cancer. This laboratory uses the tools of structural biology and biochemistry to investigate molecular mechanisms of proteins involved in repairing DNA damage and maintaining replication fork progression. Current work focuses on base excision repair of DNA alkylation damage by DNA glycosylases and repair of stalled replication forks by structure-specific DNA translocases. The long-term goals are to understand the fundamental processes underlying genome maintenance and to develop new therapeutic strategies that target genetic diseases.
