The focus of research is on cognitive function over the lifespan and implications of cognitive function (specifically executive function and working memory) on self-management of chronic disease, or in the case of children, on school achievement. Self-management is often indexed by examining medication adherence. The population of interest is older adults with hypertension and in collaboration with Dr. Ki Moore, children who are diagnosed and treated for acute lymphoblastic leukemia. Findings have implications for self-management challenges in other populations with chronic disease conditions. I have specific interest and expertise in quantitative research methods.
