Early life and education

Eigenbrode's inherent curiosity, as well as being in a family of engineers and technicians, stimulated her enjoyment of science. Geology in particular interested her and she became a "professional geology student".^[1]

Eigenbrode obtained her B.S. in geology from James Madison University in Virginia. Her senior thesis explored the clay mineralogy of river terrace soils in Virginia.^[2] Her master's degree was obtained from Indiana University Bloomington and focused on geological sciences while working under the direction of Lisa Pratt.^[3] Her Ph.D. was obtained at Pennsylvania State University where her dissertation topic was "Late Archean microbial ecology: an integration of molecular isotopic, and lithologic records"^[4] while working under the direction of Katherine Freeman. Following her Ph.D., Eigenbrode was a postdoctoral fellow at the Carnegie Institution of Washington from 2004 until 2007^[2] working under the direction of Marilyn Fogel. In 2007 she accepted a position at the National Aeronautic and Space Administration as a space scientist.^[2]

Research

Eigenbrode's early research was on the Earth's atmosphere during the Archean era where she examined organic carbon,^[5] sulfur,^[6] and the origin of aerobic ecosystems.^[7] She then moved on to examining organic compounds found in Neoarchaean rocks,^[8] establishing field methods to prepare samples for analysis,^[9] and developing methods to preserve samples from Mars in a manner that allows investigation of biosignatures.^[10][11]

Her current research focuses on Mars, and uses samples collected by the rover Curiosity which she uses to search for signals of life on Mars.^[12] She received NASA's Internal Research and Development (IRAD) Innovator of the Year award in 2009 for her work on a sample preparation module needed to collect samples from Mars.^[13] She is a part of the team^[14][15] working on samples from Mars including gases^[16] and soils,^[17] and radiation on the planet.^[15][18] She was lead author on a paper examining organic matter within the samples from Mars,^[19][20] research that used the SAM instrument (Sample Analysis at Mars) to burn samples collected from the surface of Mars and examined the resulting gas to determine the composition of the samples.^[21][22] Eigenbrode is also establishing the groundwork to use the CheMin (Chemistry and Mineralogy) instrument on Curiosity to detect organic salts in the Mars samples.^[23][24]
