Dr. Greenwood has long investigated how the aging process affects the mind and brain in the context of normal genetic variation. She has recently begun to investigate ways to ameliorate cognitive decline late in life. The ultimate goal of training in healthy older people is to improve cognitive functioning in daily life. Dr. Greenwood has shown such transfer of training in concert with changes in functional connectivity and white matter integrity in healthy older people. She is currently investigating the elements of successful training – working memory, attention, executive functioning – in young people. She also investigates use of non-invasive brain stimulation as a means of heightening effects of training on cognition, regional brain activation, functional connectivity, and white matter integrity.
