Meet the Team
A. Susana Ramírez, PhD, MPH
Principal Investigator

As an infodemiologist, Dr. Susana Ramírez applies communication science to advance public health goals for rural and Latino populations. Communication inequalities – differences in access, comprehension, and use of health information across social groups – exacerbate rather than reduce health disparities. The science of communication plays an important role in understanding where those communication failures occur, how they affect health, and how to harness the power of communication to improve health.
Dr. Ramírez is a nationally recognized expert on media, inequality and dietary health, and Latinx culture. She has provided expert testimony for the Centers for Disease Control and Prevention on communicating about obesity and chronic disease and is frequently invited to discuss communication and public health challenges facing rural and Latino populations. Her research has been published in top interdisciplinary journals and has been funded by the National Institutes of Health, Buoy Health, and the Hellman Family Foundation. Dr. Ramírez’ research has been featured in regional and national news including NPR, ABC News, Univisión, and the Huffington Post.
Currently Dr. Ramírez is an Associate Professor of Public Health Communication at the University of California in Merced. In 2019-20, she was Visiting Professor at the Nacional Autónoma de México (UNAM), through the University of California Education Abroad Programs.
Dr. Ramírez earned a PhD in Communication from the Annenberg School for Communication at the University of Pennsylvania, a Master of Public Health from Harvard University, and a Bachelor of Arts in Communication from Santa Clara University. Professor Ramírez completed a postdoctoral fellowship in cancer prevention in the National Cancer Institute’s Division of Cancer Control and Population Sciences. She has 20 years of experience designing, implementing, and evaluating strategic, culturally-appropriate communications in multinational organizations.
