Lindsay H. Ryan received her Ph.D. in 2008 from the Pennsylvania State University in Human Development and Family Studies. Dr. Ryan is an investigator on several ongoing research projects funded by the National Institute on Aging, all of which involve an interest in better measuring and understanding the processes by which adults change over the life course. Broadly, her research is focused on the ways in which psychosocial factors and contexts affect health (physical and cognitive) and well-being across adulthood. Her doctoral work paired with postdoctoral training at the Survey Research Center at the University of Michigan impacted her work by fostering a life course, multidisciplinary perspective. Her research interests include investigating individual and contextual influences on psychological well-being, physical health, and cognition across adulthood, with a particular focus on the impact of social relations. Finally, her work considers a variety of psychosocial contextual factors that may play a role in health and well-being processes in adulthood, including social relationships, age-cohort membership, and work and retirement status.
