Hensley is one of the premier researchers of some of the world's most dangerous infections, including Ebola hemorrhagic fever, Lassa fever, the coronavirus diseases Severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS),[2] and smallpox.

She also held graduate teaching and research posts at the University of North Carolina at Chapel Hill, where she achieved her PhD (advisor Ralph S. Baric),[1]and at Duke University Medical Center in Durham, North Carolina.

Hensley is the subject of a chapter in journalist Richard Preston's 2002 book Demon in the Freezer, which covers the history of smallpox eradication and the current debates over remaining smallpox stocks. In Chapter 5, "A Woman With a Peaceful Life", Preston recounts Hensley's beginnings as a researcher with USAMRIID and her eventual recruitment to the CDC to collaborate on smallpox research.
