Oanh Meyer, PhD, MASOanh Meyer, Ph.D., M.A.S. – Principal Investigator

Dr. Meyer is Assistant Professor of Neurology. She received her Ph.D. in Social Psychology from UC Davis and completed a postdoctoral fellowship there and at UCSF. Dr. Meyer’s research interests focus on social determinants of health as they affect underrepresented populations, in particular racial/ethnic minorities and older adults. She is currently examining neighborhood effects on health and she plans to continue this unique aspect of research.

Dr. Meyer also is working with her community partners to develop an intervention to help Vietnamese dementia caregivers and their family members. Having been trained as a social psychologist and collaborating with scholars from multiple disciplines (e.g., clinical and community psychology, neuropsychology, epidemiology, sociology, medicine, psychiatry), her research emphasizes the importance of utilizing innovative and interdisciplinary approaches to studying cognitive and mental health. When she is not in front of a computer, she enjoys spending time with her husband, children, and friends.

Current Research Assistants

Thuy DoDuyen Thi Ky Tran

Duyen is a third-year undergraduate student at the University of California, Davis majoring in Psychology and her career goal is to become a medical doctor. The stigma of dementia and the lack of support networks for dementia caregivers are two issues that she has become interested in researching. She wants to develop public health programs and strategies responsive to the diverse cultural values and traditions of the communities being served. She believes that her involvement with the Diversity and Disparities Lab will not only help her gain more knowledge about factors such as trauma, society, culture, and family relating to Alzheimer's disease and the effects of caregiving on patients’ health, but that it will also give her a chance to give back to the community around her.

Tiffany TranTiffany Tran

Tiffany Tran is currently a fourth-year student majoring in Human Development at the University of California, Davis. After graduating, she plans to take a year off to gain some clinical experience before applying to a physician assistant (PA) program. Growing up, she followed her mom to visit elderly patients in nursing homes where she was able to interact and spend some time with the residents. This sparked her interest to work with seniors, especially those living in underserved communities. Born and raised in San Jose, CA, where there’s a large Vietnamese population, Tiffany is eager to learn more about dementia related diseases and hopes to be able to help spread awareness of the symptoms and development of these diseases as well as to reduce the negative stigma around the topic in Asian communities.

In her free time, she enjoys cooking and baking as well as writing poetry.

Her time in the lab has inspired her to help spread awareness about Alzheimer’s and help connect caregivers in the Latino community to more resources and information.

Julia NguyenJulia Nguyen

Julia Nguyen is currently a fourth-year student at UC Davis majoring in Global Disease Biology and minoring in Human Rights. After graduation, she hopes to continue contributing to studies in the Diversity and Disparities Lab while applying to graduate school and continuing to work as a policy fellow at a non-profit organization in the State Capitol. Through her involvement in the lab, Julia has been able to connect with the local AAPI (Asian American Pacific Islander) community. She believes that personal narrative and lived experiences are a crucial part of developing culturally relevant and inclusive health interventions and policies.
