About Matias Lab
Welcome to the Matias Lab!
As a Cooperative Extension academic, Dr. Matias works on advancing research and extension centered on increasing access to healthy food, promoting health through nutrition and preventing nutrition-related chronic diseases. With a vision to increase food justice and health equity, we focus our efforts on underserved, marginalized and vulnerable populations. We use epidemiological methods and biostatistics to study biological and behavioral exposures and outcomes related to food environments, dietary practices, health and wellbeing, with a clear understanding of the social drivers of health.
