Danielle grew up on a small dairy farm in rural South Dakota and received her BS in ecology and political science from the University of South Dakota. Her PhD thesis was the investigation of the influence of membrane microdomains and, specifically, the ganglioside GM1 in ion channel function and cell signalling using mammalian sperm during fertilization as a model. Danielle's focus was with large animals, with a primary interest in public health, vector-borne disease, and livestock systems in developing countries and a background in habit management and mapping. She also expressed a strong interest in conservation and teaching.
Danielle Buttke had worked as an Epidemic Intelligence Service Officer for the Centers for Disease Control and Prevention in Atlanta, GA. She was one of only 84 Epidemic Intelligence Service officers, with her work taking her around the world.
