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]

Career

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]
