Summary of Research Studies

Our main research focus is on elucidation of the pathophysiology of isolated focal dystonia through the investigations of its neuroimaging, neuropathological, clinical, genetic and environmental correlates. We are also interested in comparisons of neural features of dystonia with other movement disorders, such as essential tremor and Parkinson’s disease. Our recent research direction includes studies on functional and structural connectomes of high frequency networks in epilepsy. Using multi-disciplinary approach and novel technologies, we are developing a better understanding of normal and diseased states of the central nervous system, which will ultimately help develop new therapeutic options for patients with movement disorders and epilepsy.
