Please see announcement for postdoctoral position below and circulate to those who may be interested. 

Postdoctoral Position at the University of Arizona and Biosphere 2

Biosphere 2 is looking for a creative post-doctoral scientist with a strong background in instrumentation and isotope and/or trace gas biogeochemistry to join an interdisciplinary “ecosystem genomics” team seeking to link biotic and abiotic processes from pores to the ecosystem scale. This is a one-year position with the possibility of renewal.

The postdoc will take a leadership role in evaluating a suite of carbon cycle tracers including carbonyl sulfide (COS), oxygen isotopes of CO2 (18O-CO2), and solar induced fluorescence (SIF). Photosynthesis cannot be directly measured at the ecosystem or global scale; thus independent tracers for photosynthesis are needed to reduce uncertainty in the responses of photosynthesis and respiration to global change to better project biosphere-atmosphere feedbacks. Carbon cycle tracers will be evaluated at Biosphere 2’s flagship research infrastructure, the Landscape Evolution Observatory (LEO,, which is the world’s largest laboratory experiment in the interdisciplinary Earth sciences and boasts an unrivaled capability to close water, carbon, and energy balance at the landscape scale. The cycling of these tracers in LEO and the B2 biomes (rainforest, desert, savanna, mangrove, ocean) will be compared to relevant genomic traits in leaves and soils.

The candidate will manage cutting edge trace gas and stable isotope instrumentation, deployed at Biosphere 2, lead interpretation of data collected from the hundreds of sampling locations in LEO, and work as part of a multidisciplinary team studying the co-evolution of biotic and abiotic features of landscapes. The candidate will add new measurement capabilities to the LEO system, which will involve the construction of new systems for gas flow, calibration, and data collection and their automation. The position is based at University Arizona, but will involve significant time commitments at Biosphere 2. These requirements will provide exceptional opportunities to learn new techniques and to make major scientific contributions to problems of both scientific and societal interest using cutting-edge technology.
