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] In 2015, Dr. Voytek formed Nexus for Exoplanet System Science (NExSS), a systems science initiative by NASA, to search for life on exoplanets.[3][4]

Fields

Dr. Voytek's primary scientific interest is biogeochemistry and aquatic microbial ecology; more particularly, 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.[5]

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".[6]
