Research Interests

Keywords: neural, genetic, and lifestyle factors that affect normal aging, brain mapping, white matter, MRI techniques, age-related brain reorganization

Numerous factors influence the aging of the brain and in part determine how well we are able to age cognitively. The KNAC lab is interested in the neural, genetic and lifestyle factors that guide this process. Our research uses structural and functional neuroimaging techniques to investigate how the health of our brain's structure supports the brain's function and how these impact our cognitive performance as we age.

Dr. Kennedy's currently funded research project involves investigating the role of white matter in the reorganization of age-related brain function using structural and functional imaging techniques. She is interested in understanding how the brain changes with age, both adaptively, and detrimentally, and how this knowledge might be used to stave off cognitive decline.
