Initiative for California American Indian Health Research and Evaluation (I-CAIHRE) 


The mission of the Initiative for California American Indian Health Research and Evaluation (I-CAIHRE) is to improve the lives of individuals in California’s American Indian and Alaska Native (AIAN) communities by conducting high-quality research that is informed by and responsive to the community’s needs and perspectives. We understand that effective change requires a deep understanding of both the challenges faced by and strengths inherent within our Native communities, which can only be achieved through gathering relevant, community-informed data. Therefore, we are committed to providing research that incorporates community perspectives and supports meaningful, sustainable improvements in health and well-being for AIAN communities in California.
