Astrogeology Science Center

Lauren Edgar is a Research Geologist at the USGS Astrogeology Science Center.  She earned her bachelor's degree from Dartmouth College in 2007, and a Ph.D. in Geology from the California Institute of Technology in 2013.  Prior to coming to the USGS, she was a postdoctoral fellow in the School of Earth and Space Exploration at ASU.  Lauren is an active member of the Mars Science Laboratory and Mars Exploration Rover science teams, serving as the Geology and Mineralogy Theme Lead on MSL, and as an uplink and downlink lead for several instruments on MER.  Her research aims to understand martian surface processes through the use of rover and orbital observations and terrestrial field analogs.  She uses sedimentology, stratigraphy and geomorphology to infer past processes involving water, wind, ice, and volcanic activity, and to identify potentially habitable environments on Mars.
