For the past two decades, the Christopher Pearson lab has studied the mechanisms of disease-causing repeat instability associated with neurological, neurodegenerative, and neuromuscular disease, with the goal of developing effective treatments. In addition to a focus on how DNA repair can drive disease-causing repeat mutation, his lab also studies how DNA repair can protect against cancer-causing mutations. He has published over 95 peer-reviewed studies.<\/span><\/p>\n<\/div><\/div><\/div>
