Sarah Stewart Johnson is an American biologist, geochemist, astronomer and planetary scientist. She joined Georgetown University in 2014 [1] and is currently the Provost's Distinguished Associate Professor of Biology and the Science, Technology, and International Affairs program in the School of Foreign Service. [2]
Johnson was born in Kentucky and grew up in Lexington. [3] She received her bachelor's degree from Washington University in St. Louis, where she was an Arthur Holly Compton Fellow and majored in math and environmental studies. During college, she won a Goldwater Scholarship and a Truman Scholarship. [3] [4] [5] Johnson then attended Oxford as a Rhodes Scholar where she earned bachelor's and master's degrees. [6] [1] In 2008, she completed a PhD in planetary science at MIT. [7]
Johnson was a Junior Fellow at Harvard University from 2008-2009 and 2011-2013. [8] She was a White House Fellow working for the President’s Science Advisor, under the Obama administration from 2009-2011. [9] Johnson became a faculty member at Georgetown in 2014. Her work involves the use of analog environments to study the habitability of the surface and subsurface of Mars and icy moons. [10] [9] Her lab at Georgetown is currently focused on the detection of agnostic biosignatures, sometimes referred to as "life as we don't know it". [11] [12] She is a visiting scientist at NASA's Goddard Space Flight Center with the Planetary Environments lab. [13] She participated in the Curiosity, Opportunity, and Spirit missions. [6] [3]
