Dr. Mary A. Voytek is a microbiologist with the United States Geological Survey (USGS) in Reston, Virginia, and director of the National Aeronautics and Space Administration (NASA) Astrobiology Program at NASA Headquarters in Washington, D.C.[1][2]
Dr. Voytek's primary scientific interest is biogeochemistry and aquatic microbial ecology, in particular environmental controls on microbial transformations of nutrients, xenobiotics, and metals in freshwater and marine systems. Voytek has worked in several extreme environments including Antarctica, hypersaline lakes, deep-sea hydrothermal vents, and terrestrial deep-subsurface sites. She has conducted deep-biosphere studies at the Chesapeake Bay Impact Structure.[2]
Voytek is a member of the American Geophysical Union since 1990.[3]
At the United States Geological Survey, she heads the Microbiology and Molecular Ecology team.[2]
She took charge of the NASA Astrobiology Program on September 15, 2008, as Interim Senior Scientist for Astrobiology in the Science Mission Directorate at NASA Headquarters.[2]
In December 2010, she defended a news release of NASA on the possibility there might be a principally wider basis of life than so far assumed, following conclusions of a study by Felisa Wolfe-Simon on the arsenic-eating bacterium GFAJ-1, as presenting a "phenomenal finding".[4]
