She is the Director of the X-linked Dystonia and Parkinsonism (XDP) Brain Bank and oversees dissection, processing and distribution of brain tissue for XDP research. She also conducts research using patient-derived induced pluripotent stem cells to study abnormal RNA and DNA structures that contribute to neurodegenerative diseases, including Huntington’s disease and XDP. The goal of this research is to identify common pathways that lead to neurodegeneration and may be targets for drug development.
