The Laboratory of Geology of Lyon (Université Lyon 1 & ENS de Lyon, France) invites applications for a postdoctoral research associate in environmental microbiology – biogeochemistry. The project is part of the multi-disciplinary consortium Science For Clean Energy (S4CE) funded by the European Union’s Horizon 2020 research and innovation programme. S4CE has been established to understand the underlying mechanisms underpinning sub-surface geo-energy operations and to measure, control and mitigate their environmental risks. The PDRA will work in close collaboration with an international group of scientists on deciphering the role of the subsurface biosphere in the C, N and S biogeochemical cycles affecting energy-generating geo-operations. Research focuses on the analysis of the metabolic activity of key microorganisms that develop at depth in geothermal wells and CO2/H2S injection wells for enhanced geothermal energy (EGT) and carbon capture sequestration (CCS), respectively. Sampling of underground fluids is scheduled at two sites in 2018. The goal of the project is to characterize the metabolism of key microorganisms under subsurface conditions. The research involves the cultivation of various microbial strains of relevance for the sampled subsurface environments under simulated conditions of the subsurface (high pressure and/or high temperature). A unique pressure facility is available at the LGL allowing monitoring of metabolic reactions using in situ spectroscopy. The candidate should hold a PhD in microbiology with expertise in environmental microbiology and microbial physiology. An experience in microscopy and spectroscopy is appreciated but not required. Complete applications will be reviewed every two weeks, starting now, until the position is filled.
