Shelby Hintze Jepperson is a doctoral student and public health professional. A biology major and naturalist intern during her undergraduate education, she began to understand the importance of providing practical information and engaging the community to increase awareness of environmental health. Now she enjoys teaching about how climate change effects our health and what we can do to make impactful changes. Growing up in an electric passive solar home, she learned about the importance of sustainability through the habits of her parents and grandparents.
