Using the lessons and experiences of AIAN Elders, Jordan’s research develops generative-based approaches to improve the health of all generations.
Jordan’s research agenda has made significant contributions to the field with discussions on culture-specific approaches to successful aging, including the development of a model of Alaska Native successful aging, a theory of AN healthy aging, and the concept of Indigenous cultural generativity. His research has identified indigenous cultural generativity as a critical ingredient to successful aging, which has important implications for the wellbeing of AI/AN people, including those with ADRD, their caregivers, and family and community members.
