Caltech’s MS in Geobiology enables students to explore the intersection of life and Earth’s physical environment across geological time. From early microbial life to modern biosignatures, the following research topics offer deep scientific discovery.
Stable Isotope Analysis of Ancient Microbial Mats
Detection of Biosignatures in Mars Analog Environments
Microfossil Characterization in Precambrian Sedimentary Rocks
Role of Microbes in Biogeochemical Sulfur Cycling
Investigating Biomineralization Processes in Modern Stromatolites
Paleoenvironmental Reconstruction Using Organic Geochemistry
Geobiological Signatures of Anoxygenic Photosynthesis
Modeling Microbial Ecology in Hydrothermal Vent Systems
Preservation of Biosignatures in Impact-Generated Rocks
Evaluating the Habitability of Extreme Terrestrial Environments
Archaean Ocean Chemistry and its Link to Early Life Evolution
Lipid Biomarkers as Indicators of Ancient Metabolisms
Microbe-Mineral Interactions in Ferruginous Settings
Sediment Diagenesis and its Effect on Geochemical Proxies
Astrobiological Implications of Earth’s Early Biosphere
