Overview


I am a bilingual gerontologist (Spanish/English) with expertise in the epidemiology of aging. My research focuses on how environmental exposures—the exposome—affect cognitive function and the development of Alzheimer’s disease, related dementias, and other neurodegenerative conditions such as Parkinson’s disease. I explore a range of factors, including pesticide and toxic chemical exposure, social determinants of health, traumatic brain injury, metabolic biomarkers, cognitive resilience, and interventions such as cognitive training. I am also interested in research involving artificial intelligence and machine learning methodologies. I welcome opportunities for academic collaboration.
