Posting Number: req17491

Department: Environmental Science-Res

Location: Main Campus

Address: Tucson, AZ USA

Position Highlights

The Tfaily lab at the Department of Environment Science at the University of Arizona seeks a highly motivated and talented postdoctoral researcher to join the lab to work on understanding the fate of carbon in permafrost soils and its implications for climate change. This position offers a unique opportunity to contribute to cutting-edge research in a rapidly evolving field. Permafrost soils contain a vast reservoir of carbon, larger than the amount of CO2 in the atmosphere. As global temperatures rise and permafrost thaws, the release of this carbon into the environment becomes a critical concern. The fate of this carbon, whether it remains sequestered or is released as greenhouse gases, is still uncertain. Furthermore, permafrost thaw introduces geophysical hazards and can lead to unpredictable changes in hydrological flows. This project aims to address these challenges by investigating the early stages of permafrost thaw and its impact on carbon dynamics through the lens of metabolomics and multi-omics integration. This includes but not limited to (i) Conducting fieldwork across permafrost thaw gradients, focusing on the thawing interface; ii) Collect and analyze samples to identify "indicator chemicals" that can detect degrading permafrost before surface observations reveal visible signs of thaw; iii) Investigate the relationship between these indicator compounds and thaw depth, water content, porosity, and biogeochemical soil conditions. vi) Perform targeted incubations to assess the role of these compounds in fueling carbon emissions. V) Collaborate with an interdisciplinary team and contribute to the development of a framework for early detection of permafrost thaw and understanding its impact on climate change. Reviews of applications will begin mid-August 2023.
