Quincy Samus, Ph.D.

Associated Investigator

Dr. Samus' research interests are focused on developing cost-effective ways to deliver dementia care to older adults with memory disorders who live in the community. She has developed a person-centered, coordinated care model for older adults with memory problems, and is seeking to determine if this approach enables individuals to remain at home longer, with a higher quality of life, than standard methods of care.
