Overview
The DAR team is committed to advancing science that addresses neurocognitive disparities and promotes neurocognitive health equity in aging. We aim to develop accessible, sustainable, and ethical research that includes and benefits all by focusing our efforts on groups that have been underrepresented in science. We seek to promote an environment that fosters a sense of belonging in science among trainees, staff, and faculty from all backgrounds that allows all to thrive.

Lizbeth Vera Murillo, MS
Hola! I am a bilingual (English/Spanish) clinical research coordinator, originally from Ecuador. I obtained my Bachelor’s in Psychology at Youngstown State University and my Master’s in Psychological Science at the University of North Florida. My research focuses on neurocognitive health equity for Latinos/Hispanos and Black/African Americans, mainly through promoting the recruitment and retention of these groups in research studies. In my current role at Duke, I am focused on helping the lab address neuropsychological test standards for Spanish Speakers with the LAMP (Latinos, Memoria y Pensamiento) study and prevent cognitive problems with our Parkinson’s study.
Eric Griffith, PhD
Dr. Eric Griffith received his Ph.D. in anthropology from the University of Massachusetts Amherst and then worked as a Postdoctoral Fellow at Duke's Samuel DuBois Cook Center on Social Equity. He completed his dissertation fieldwork in central Mexico, focusing on the experiences of familial caregivers for people living with Alzheimer’s disease. Eric’s research interests include biocultural anthropology, cognitive aging, health disparities, and social determinants of health. He is currently an Assistant Professor of Cultural (Medical) Anthropology at Utah State University, where he collaborates with our lab.
Leo Sanabria
Leo Sanabria is a senior at Duke University, majoring in Biology with a strong interest in health equity and neurocognition. He is interested in understanding how the lived experiences of Latino communities shape cognitive health and healthcare outcomes, particularly in comparison to other populations. He is especially curious about how structural and cultural factors—such as language, socioeconomic status, and access to care—contribute to disparities in cognitive aging and disease presentation. More broadly, Leo is committed to research and initiatives that center racial and ethnic minorities in healthcare, to advance more equitable, accessible, and culturally responsive care.
Fabiana Henríquez
¡Saludos! My name is Fabiana Henríquez, and I am a bilingual (Spanish/English) clinical research assistant born and raised in Puerto Rico. I am currently a sophomore at Duke University pursuing a degree in Neuroscience on the pre-med track. I have been working as a clinical research assistant for a semester, where I have been taught to administer patient visits for Parkinson’s disease and Hispanic neurocognitive norm studies. In this role, I conduct sociodemographic and neuropsychological assessments with Hispanic patients in North Carolina, among other tasks in the lab. In the near future, I aspire to become a neurologist specializing in neurodegenerative diseases and to use my work to support the Hispanic community. Outside of academics and research, I love photography and video editing!

Amber White
I am a senior at Duke University majoring in Biology, and I am passionate about bridging healthcare and Native American communities through research. As a member of the Navajo Nation, I care about advancing health equity and ensuring that Indigenous voices as well as other underrepresented groups are represented in science and medicine. I am especially interested in how research can be used to understand and address health disparities in aging, cognitive health, and healthcare access. My goal is to pursue a career in medicine and research that centers cultural relevance, community engagement, and promote equity for Native communities and other marginalized groups.
