Mikucki's work on Blood Falls was the first to describe the microbiology and geochemistry of the feature.[5][6] Career and impactAs a postdoctoral fellow at Harvard University (2006–07) and Dartmouth College (2008), and a professor at the University of Tennessee,[7] Mikucki continued her work at Blood Falls. Mikucki's work demonstrated that microbes can grow below ice in the absence of sunlight by using sulfate and iron to help them metabolize organic matter.[1][2] Her continuing work at Blood Falls[8][9] led to the discovery of a network of salty groundwater beneath Antarctica's McMurdo Dry Valleys, which is likely the source of the Blood Falls outflow, and a habitat for subsurface microorganisms. The work was also the first ever use of airborne resistivity in Antarctica.[10] Mikucki was part of the first team to drill into and sample an Antarctic subglacial lake, which demonstrated the existence of life deep beneath Antarctic ice for the first time.[11] Selected works
