Our team and approach

We are a mix of health educators, data analysts, communication and policy experts, and research scientists, who work together using our breadth of skills and depth of knowledge to mobilize data for public health.

We use GIS and analysis to understand and visualize trends in data and utilize storytelling and interviews to explore individual and community level impacts. We create maps, infographics, storymaps, and videos, alongside published papers and conference papers to share our work.
