Some of the topics and research questions I am currently working on include:

  • Operationalizing energy vs fatigue, delineating the underlying neurobiology of each construct, and exploring their functional correlates

  • Evaluating perceived energy in the context of successful aging and how energy fits within and relates to constructs such as vitality, motivation, and purpose in life

  • Determining how energy and energy decline relate to mobility in aging

  • Assessing energy as a potential cause of parkinsonian signs in healthy older adults and as a potential prodromal signal for Parkinson's Disease

  • Exploring the underlying neural networks behind perceived energy in those with Alzheimer's Disease and Mild Cognitive Impairment
