Dr. Poston'’s research interests include the development, validation and application of functional and structural neuroimaging as biomarkers for the diagnosis and treatment of movement disorders. Specifically, her research focuses on using FDG PET and fMRI to understand abnormal brain networks that lead to both motor and cognitive dysfunction in patients with parkinsonism. She is also interested in the development of novel imaging analysis techniques for establishing diagnosis and monitoring disease progression in early parkinsonian disorders, such as Parkinson’s disease, multiple system atrophy, progressive supranuclear palsy, and corticobasal degeneration. Such techniques can be used in the development and testing of novel therapeutic interventions, such as gene transfer therapy in Parkinson’s disease.
