My program of research focuses on the interpersonal context of chronic illness with particular emphasis on how and why members of the care dyad are similar and different in their appraisals of the illness context. I am interested in the impact this similarity/difference has on management of the illness by the couple or family dyad and ultimately how it impacts the health and well-being of both members. I have taken a unique dyadic perspective throughout my career to view the older adult and their family member providing care as a team. I strongly believe this perspective sheds important light on the illness and care experience and will lead to more ecologically-sound and effective interventions. I have published extensively across disciplines. All of my research has involved interdisciplinary teams; something I highly value and believe essential. Nearly 20 years of empirical evidence culminated in the publication of the Theory of Dyadic Illness Management.
