I am passionate about understanding the mechanisms related to physical health and cognitive functioning within diverse adult populations (e.g., Black/African American adults; older adults with restricted socioeconomic resources). I have collaborated on several, large longitudinal projects (e.g., the autopsy study of the Baltimore Longitudinal Study of Aging (BLSA) and the Johns Hopkins Alzheimer’s Disease Research Center, the Johns Hopkins Sleep Dream Team, Baltimore Study of Black Aging (BSBA), and Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS)) and shared research findings in a variety of outlets (e.g., scientific publications, scientific/community presentations, news articles, and podcast interviews). Beyond conducting research, I am interested in mentoring the next generation of academic scholars, especially from underrepresented backgrounds in scientific research.

Research Interests

Dr. Gamaldo’s research focuses on identifying adverse (e.g., poor sleep, financial strain, and social stressors) and protective factors (e.g., education, life satisfaction and social support) associated with cognitive functioning, particularly in populations at risk for AD/ADRD diagnosis. Dr. Gamaldo is also interested in supporting research that explores the utility of digital health assessments in diverse older adult populations.
