Working together to build healthy communities in California
EHSC’s Community Advisory Committee (CAC) brings together community-based organizations, public agencies, and academic researchers to collaborate on the design and implementation of environmental health science research at UC Davis. CAC members provide valuable connections to the experiences and perspectives of the communities where environmental health research is most relevant.
The overarching purpose of the Community Advisory Committee (CAC) is to ensure that EHSC-supported research is:
- Responsive to the needs and priorities of those most impacted by environmental health issues in California
- Policy-relevant and accessible to community stakeholders, advocates, and government actors
- Leads to meaningful changes in exposures and health outcomes in vulnerable communities
