Dr. Verschoor research interests include:

  • Chronic inflammation as a mechanism of age-related immune dysfunction and altered vaccine responses.
  • Determinants of adverse health-related outcomes in older adults in community and clinical settings.
  • Cellular and molecular biomarkers of disease and poor health trajectories.
  • Development and application of measures of biological aging.
