NASA scientist David J. Des Marais, the Hamilton Visiting Scholar in Geophysics for SMU’s Huffington Department of Earth Sciences, will present two departmental lectures and one public lecture Nov. 17-20.
Des Marais will deliver his free, public lecture, “Life on Mars,” at 7 p.m. Nov. 17 at the Frontiers of Flight Museum, 6900 Lemmon Avenue, at the southeast corner of Love Field.
His departmental lectures will be from noon to 1 p.m. in 153 Heroy Hall:

Des Marais is a staff scientist at NASA Ames Research Center, where he is an interdisciplinary scientist for astrobiology on both the Mars Exploration Rover 2003 science operations working group and the Mars 2005 CRISM infrared spectrometer. His areas of specialization have included the stable isotope geochemistry of carbon in lunar samples, meteorites and oceanic basalts, the biogeochemistry of microbial communities in hypersaline environments, and the biogeochemistry of ancient (Precambrian) carbonates and organic matter.
