Psychosocial Factors in Aging and Neurodegenerative Disease. The overall aim of my research program is to understand how psychosocial experiences influence late-life cognitive trajectories and the expression of neurodegenerative disease. I have examined several putative risk (e.g., depressive symptoms, psychosis) and protective (e.g., educational attainment, bilingualism) factors in the prediction of dementia incidence and course. My current interest is in the role of positive psychosocial factors (e.g., wellbeing, self-efficacy, social support) in cognitive and brain aging, independent of negative affect. Ultimately, I wish to understand how these psychosocial factors contribute to brain maintenance or reserve.
Psychosocial Factors and Racial/Ethnic Diversity in Cognitive Aging. I investigate interactions between psychosocial factors and race/ethnicity in order to (1) identify causes of disparities in late-life cognitive outcomes, (2) determine whether key risk and protective factors differ across groups, and (3) explore how the unique psychosocial experiences of racial/ethnic minorities shape late-life cognitive trajectories.
Statistical Modeling of Symptom Trajectories in Aging and Neurodegenerative Disease. Advanced longitudinal methods such as latent growth curve modeling represent powerful, flexible techniques for characterizing inter-individual differences in intra-individual changes in brain and behavior over time. I am interested in modeling multivariate outcomes longitudinally to explore theories of disease progression, identify sources of individual differences in aging and disease, and improve clinical prognosis.
