About this position

Texas A&M University is recruiting a postdoctoral researcher in the Department of Geology to work on carbon-oxygen (“clumped”) isotope resetting kinetics in carbonate minerals.

The project centers on heating experiments designed to quantify how carbonate minerals record and reset isotopic signals. The postdoc will analyze samples with a stable light-isotope-ratio mass spectrometer (IRMS), model experimental results, and use established clumped-isotope reordering approaches to interpret the kinetic data.

Day-to-day research activities include preparing and characterizing samples using thin-section petrography, scanning electron microscopy, and related techniques, as well as conducting heating experiments that involve loading and sealing samples in quartz tubes. The position also includes routine maintenance and repairs on the 253 Plus IRMS and the automated carbonate reaction system.

The successful candidate will join the Department of Geology & Geophysics at Texas A&M University in College Station, a large research university with a strong earth-science program and established facilities in geology and geophysics. The role is oriented toward producing publishable results, with manuscript preparation and submission as a key responsibility.

Funding details

Funded through an NSF grant; future employment may be contingent upon future funding. Salary is commensurate.

What's required

Ph.D. in Geology or equivalent science is required. The preferred candidate will have 2 years of experience performing clumped isotope analyses on carbonate minerals, preferably on a Thermo Fisher Scientific 253 Plus IRMS system with Kiel automated carbonate system; experience conducting clumped isotope heating experiments; experience using clumped isotope reordering models and programs such as the Isotopylog Python package; 2 years of experience with simple maintenance and repairs on an IRMS; scientific curiosity; ability to write scientific papers; and experience using vacuum lines for gas handling systems. The role also requires the ability to lift, carry, load, or unload heavy instructional materials.
