Research Interests

Our goal is to understand the role of the DNA damage response in the nervous system, and how this functions to prevent disease. The response to genotoxic stress is a prerequisite for development of the nervous system. Mutations in a variety of DNA damage-response factors can lead to human diseases that are characterized by pronounced neuropathology. In many of these syndromes the neurological component is amongst the most deleterious aspects of the disease. Because the nervous system poses a particular challenge in terms of clinical intervention, understanding how DNA repair deficiency impacts the nervous system will be important for design of therapies targeted at ameliorating neuropathology including neurodegeneration and brain tumors.
