Jordan P. Lewis is Aleut and Sugpiaq, and his family is from the Naknek Native Village in southwest Alaska and Cannon Beach, Oregon. He is the Director of Research for the Center for One Health Research and a Research Professor with the College of Indigenous Studies at the University of Alaska Fairbanks. He holds a Ph.D. in Community Psychology from UAF, an MSW from Washington University in St. Louis, and a BSW from UAF, and is a certified professional gerontologist. Trained as a cross-cultural community psychologist and gerontologist, Jordan has worked with American Indian and Alaska Native (AI/AN) communities to identify characteristics that enable Alaska Native Elders to age successfully, or age in a good way, and become role models for their families and communities. Using the lessons and experiences of AIAN Elders, Jordan’s research develops generative-based approaches to improve the health of all generations.

Professor Feliciano Villar, PhD, is a developmental psychologist at the University of Barcelona. His main research interest is to explore and promote the contributions of older people to their communities and families, using the concept of generativity in later life. He is currently researching which generative expressions are more common among older people, both in successful and not-so-successful (what could be called ‘aging on the margins’) older people collectives, and what their impacts are in terms of personal growth and social development. He has directed more than 10 research projects funded by competitive national and European calls. He has published more than 100 papers in international academic journals based on his research. He has recently co-authored a book titled 'The development of generativity across the life span’, published by Oxford University Press. He is also the coordinator of the Master's degree on Psychologerontology of the University of Barcelona.
