Sharee Light, PhD, Assistant Professor of Psychiatry

  • Director, Neuropsychology at New Hampshire Hospital
  • Clinical interests: Clinical neuropsychological and psychological evaluation of adults with an emphasis on changes in positive affectivity, social cognition, and executive function associated with neurological disorders (such as dementia, demyelinating diseases, stroke, and traumatic brain injury) and/or psychological disorders (such as Major Depressive Disorder, bipolar disorder, and schizophrenia); and improving the assessment of affective states during the course of the traditional clinical neuropsychological assessment.
  • Research interests: Affective neuroscience and clinical neuropsychology; particularly the role of the prefrontal cortex in modulating emotional experience with foci on positively valenced emotions such as joy and social-cognitive emotions such as empathy; study of anhedonia as a transdiagnostic symptom—as it cuts across several disorders including Major Depressive Disorder, schizophrenia, Parkinson’s disease, and some forms of dementia. Neuroimaging tools used to carry out this research include fMRI, rTMS, EEG, and EMG.
