Research Interests

Current research focuses on psychophysiological and behavioral signatures of cognitive/emotional change associated with normal aging and Parkinson disease and novel treatment approaches for apathy and executive dysfunction. Her laboratory uses a variety of different tools to investigate hypothesis driven research ranging from transcranial magnetic stimulation, psychophysiology/electrophysiology (ERP), face digitizing, computational modeling, to experimental cognitive probes.
