Research and Teaching Interests

My research interests generally include investigating the underlying neural mechanisms of neuropsychiatric symptoms in neurodegenerative disorders, such as Parkinson’s disease. Studies utilize structural neuroimaging methods and/or longitudinal statistical modeling to examine predictors of cognitive impairment, apathy and depression. One line of research is testing the hypothesis that disruptions in the microbiome (gut-brain health) contribute to cognitive impairment and white matter changes in Parkinson’s disease. A second line of research focuses on relating neuropsychiatric symptoms to meaningful outcomes such as diagnostic markers of cognitive impairment and quality of life.

The goal of this study is to determine the association between microbiome disruption and markers of neuroinflammation/cognitive impairment.
