The School of Natural Resources and the Environment at the University of Arizona (UA) seeks a postdoctoral researcher to work on a new project funded by the Department of Energy on how trace volatile organic compounds (VOCs), produced by microbial, plant, and
abiotic processes, mediate below ground plant and microbial interactions by extending the rhizosphere and enhance soil carbon storage.
<div style="margin:0px"><br>
</div>
<div style="margin:0px">The postdoc will help with field and lab experiments to determine how plant productivity, root biomass, and plant growth stages influence soil carbon through VOC-mediated processes in an agroecosystem of the bioenergy crop sorghum. Specifically,
soil VOC concentrations will be measured using novel automated soil gas probes connected to an online proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF-MS) to track changes in soil VOC interactions directly in the rhizosphere of different
variants of sorghum with their traits measured overhead by a gantry ‘scanalyzer’ at the Maricopa Agricultural Center (MAC; https://mac.arizona.edu/). The postdoc will also contribute to field work at the Blodgett Forest Research Station (https://forests.berkeley.edu/forests/blodgett)
in California to help determine the impact of deep soil warming on soil carbon in the coniferous forest. The postdoc scholar will deploy, operate, and maintain VOC meausrements at the MAC site and UArizona labs and they will enhance identification with gas
chromatograph-mass spectrometer systems. The specific expected outcome of this work will be new understanding of the role of VOCs in soil C cycling and stabilization and in soil ecological and metabolic interactions.</div>
<div style="margin:0px"><br>
</div>
The position will be based at the University of Arizona in Tucson, Arizona and the postdoc will join an interdisciplinary team from UA, Lawrence Berkeley National Lab, and Aerodyne Research, Inc. The postdoctoral candidate’s development will be facilitated
through integrative interactions, constructive assessment, and support by all institutions on the project. The postdoc will actively participate in research, management, and communication activities, and will be encouraged to engage in research across institution
representing university, national lab, and industry settings. Additional postdoc activities organized within the project include instrument calibration, maintenance, and configuration of experiments, data analysis, talks, preparation of publications, and project
meetings.<br>
