Astrobiology at UCLA: An Integrated Multidisciplinary Approach to Research and Education
RESEARCH at UCLA is now focused on six main themes: (1) extrasolar planetary systems; (2) geobiology and geochemistry of early Earth and Mars; (3) evolution of Earth’s early life; (4) genomic evolution and the tree of life; (5) celestial influences on the terrestrial environment; and (6) exploration for life in the Solar System. Over the past year, some of these themes have grown significantly; the thrust of the last has been seriously compromised by the successive losses of both the Mars Climate Orbiter and the Mars Polar Lander.

The Environment of Prebiotic Earth and the Origin of Life: Experimental Approach
Our group at SUNY-Stony Brook has focussed on two research projects: a) rate of CO hydration and stability of formate and b) reduction of dinitrogen to ammonia catalyzed by minerals.

Coevolution of Life and Planets
The Kirschvink lab has focused on several aspects of interest to the National Astrobiology Institute during the past 1.5 years, including evaluation and identification of Precambrian biosignatures, testing the Panspermia hypothesis with the Martian Meteorite ALH84001, placing constraints on Life on Europa, assessing effect of the Paleoproterozoic รข??Snowball Earth’. Members of the group include Postdoctoral Scholar J.W. Hagadorn, JPL Postdoctoral visitor Eric Gaidos, Graduate Student Benjamin Weiss, and Undergraduate Students Francis Macdonald and Tim Raub.
