Hamilton Visiting Scholar to discuss life on Mars

NASA scientist David Des MaraisNASA 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:

  • Nov. 18: “Early Evolution of Earth Biogeochemical Carbon Cycles”
  • Nov. 20: “Marine Microbial Mat Ecosystems and Earth’s Early Biosphere”

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.

Renowned planetary geophysicist is SMU’s Hamilton Visiting Scholar

Don L. AndersonDon L. Anderson, renowned geophysicist and author of A New Theory of the Earth, will lecture as SMU’s Hamilton Visiting Scholar in Earth Sciences at 7 p.m. Feb. 25 in Crum Auditorium, Collins Executive Education Building. The lecture is free and open to the public and is presented by the Huffington Department of Earth Sciences in Dedman College.

Anderson will speak on “The Subterranean Cycle: The Continental Drip Hypothesis.” His theory for the Earth places plate tectonic evolution, hot spot volcanism, and the breakup of continents into an evolutionary framework more consistent with insights from other planets.

Winner of the Royal Swedish Academy’s prestigious Crafoord Prize, Anderson is the Eleanor and John R. McMillan Professor Emeritus of Geophysics at California Institute of Technology. He was director of the Seismological Laboratory of the California Institute of Technology from 1967-1989 and was elected to the National Academy of Sciences in 1982.
