Dr. Eleanor Hayes-Larson is an epidemiologist whose research program integrates social, psychiatric, and neuroepidemiology with advanced statistical methods to understand drivers of cognitive decline and dementia incidence and disparities. Her work takes a lifecourse perspective to examine psychosocial determinants of Alzheimer’s disease and related dementias in diverse populations, with an emphasis on groups historically underrepresented in research. A main line of her research seeks to evaluate the impact of traumatic stress across the lifecourse on cognitive decline, dementia, and neuroimaging biomarkers. In addition, she has a line of methodological research, including both statistical simulation studies and empirical data analysis, that focuses on improving statistical tools for causal inference and generalizability of findings in cognitive aging research.
