Adriana Arcia, PhD

Adriana Arcia

Adriana Arcia, PhD, assistant professor of nursing, studies information visualization as a way to overcome the challenge of limited health literacy, making it easy for patients to understand and use information to manage their health.

Visualization can help family caregivers understand how caregiving affects their own health status, she has found, and thus motivate them to take beneficial actions, such as doing yoga or getting caregiving help. This study, and others focusing on Hispanic populations, are crucial to addressing the information needs of Hispanics and other underserved populations.
