In general, my research falls within the category of Cognitive and Clinical Neuropsychology, with an emphasis on the cognitive sequelae associated with aging and neurodegenerative disorders. Using a multidisciplinary approach that incorporates techniques and principles from clinical science, cognitive psychology, and cognitive neuroscience, my research extends beyond the characterization of cognitive impairment in neurodegenerative disease in an effort to elucidate the mechanisms and underlying psychological processes. More specifically, I am interested in developing a better understanding of the attentional and executive functioning deficits associated with movement disorders (e.g., Parkinson disease) and how they relate to the neuropathology, treatment, and comorbid psychiatric disorders. This research has important implications for the understanding and treatment of movement disorders, as well as the more general advancement of knowledge regarding the functions of the basal ganglia and frontal-striatal circuitry.
