<p>Close All</p> <p>Job Summary</p> <p>The Geochemistry and Geomicrobiology Lab, led by Professor Alexis Templeton, investigates the reactions that occur between fluids and mafic and ultramafic rocks, in the presence and absence of microbial organisms. The Geochemistry and Geomicrobiology Lab is seeking a postdoctoral scientist to expand field and laboratory-based investigations of mineral hydration and oxidation reactions that produce hydrogen gas. This will include the spectroscopic and mineralogical characterization of Fe-bearing rocks reacted with natural fluids. Research will also include fieldwork in deep well systems to quantify the flux of hydrogen and the combined geochemical and biological processes contributing to the production and consumption of gases.</p> <p>CU is an Equal Opportunity Employer and complies with all applicable federal, state, and local laws governing nondiscrimination in employment.
