My research interests are in the neuropathological study of degenerative neurological diseases, particularly hereditary ataxias and the CNS manifestations of myotonic dystrophy. I am actively collaborating with the laboratories of Harry Orr, Laura Ranum and John Day on these projects. I am studying both the human forms of these diseases as well as transgenic models in which human mutations are expressed in mice. The focus of my laboratory is on structural pathological changes using immunohistochemical techniques.
