Overview

Gene E. Alexander is affiliated with the University of Arizona in the United States and has made contributions primarily in the fields of Medicine and Neuroscience. Their work spans several subfields including Cognitive Neuroscience, Psychiatry and Mental Health, Physiology, Radiology, Nuclear Medicine and Imaging, and Neurology.

Their research has focused on core topics such as Functional Brain Connectivity Studies, Dementia and Cognitive Impairment Research, Neural and Behavioral Psychology Studies, Physical Activity and Health, Obesity, Physical Activity, Diet, Health Disparities and Outcomes, and Advanced MRI Techniques and Applications.

Alexander's recent scholarly output includes noteworthy papers such as:

  • "Sedentary Behavior and Incident Dementia Among Older Adults" (2023, JAMA)
  • "The Role of Resting-State Network Functional Connectivity in Cognitive Aging" (2020, Frontiers in Aging Neuroscience)
  • "Exposure to Air Pollution and Risk of Incident Dementia in the UK Biobank" (2022, Environmental Research)
  • "Sedentary Behavior and Lifespan Brain Health" (2024, Trends in Cognitive Sciences)
  • "Leisure-Time Sedentary Behaviors Are Differentially Associated with All-Cause Dementia Regardless of Engagement in Physical Activity" (2022, Proceedings of the National Academy of Sciences)

Alexander has frequently collaborated with several coauthors, most prominently with Pradyumna K. Bharadwaj, David A. Raichlen, Georg A. Hishaw, Adam J. Woods, and Ronald A. Cohen.

Their work has been published in various venues with multiple contributions, including:

  • GeroScience
  • Journal of the International Neuropsychological Society
  • Frontiers in Aging Neuroscience
  • bioRxiv (Cold Spring Harbor Laboratory)
  • Alzheimer's & Dementia

The research topics covered by Alexander involve multidisciplinary approaches, often combining neuroscience, medicine, and behavioral psychology to examine the mechanisms underlying cognitive decline, dementia, and brain health across the lifespan, as well as the influence of lifestyle factors such as physical activity and sedentary behavior. Their work also incorporates advanced imaging techniques to explore brain connectivity in aging populations.
