Leanna Ehrlich came to Emory University to get a Master of Public Health degree in the global health department. Her focus was on chronic disease related to diet and physical activity, and she planned to complete summer requirements for the degree in her field. Ehrlich had worked in other public health venues, which included a year in Nicaragua for Global Brigades, a nonprofit health and sustainable development organization, followed by four years at a Boston public health research and consulting company, all focusing on chronic disease. “I had very little interest or experience in infectious disease,” she noted.
