ARES Lindsay P Keller

Biography

Lindsay Keller is a planetary scientist and manager of the Electron Beam Analysis Labs within the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center. Keller completed his National Research Council postdoctoral fellowship at Johnson and then worked in Atlanta as a materials scientist in the private sector before returning to Johnson in 2000. Currently, Keller’s research group focuses on the atomic-scale minerology and chemistry of comets, meteorites, asteroids and lunar samples. Additionally, Keller is a co-investigator on the OSIRIS-Rex mission to return samples of asteroid Bennu.
