PhD Position in Microbial Physiology and Biotechnology: Physiology and Ecology of Methanogens Job at PhD Full Time

The Microbial Physiology and Resource Biorecovery Laboratory (MICROBE), led by Dr. Wenyu Gu at the Swiss Federal Institute of Technology Lausanne (EPFL), invites applications for a fully funded PhD position in Microbial Physiology.

We are seeking a highly motivated and talented PhD student to join our interdisciplinary team at the Institute of Environmental Engineering. The successful candidate will conduct cutting-edge research in applied and environmental microbiology, with a focus on the physiology and genetic regulation of methane-producing archaea (methanogens). These microorganisms play a central role in the global carbon cycle by mediating the terminal steps of organic matter degradation in anoxic environments. Their activity serves as a critical gatekeeper of energy flow in oxygen-depleted ecosystems, including wetlands, sediments, animal digestive tracts, and anaerobic digesters, where they catalyze the final stages of anaerobic carbon mineralization.

The research will investigate how methanogens respond to dynamic environmental conditions and interact with other members of microbial communities, advancing our understanding of the ecological mechanisms governing methane production and informing future biotechnological applications. The project will combine a range of experimental and computational approaches, including high-throughput sequencing and bioinformatics, microbial isolation and cultivation, physiological characterization of gas-utilizing microorganisms, and co-culture and community function analyses.

The PhD candidate will collaborate closely with other PhD students and postdoctoral researchers, both within the laboratory and across EPFL’s international research network.
