PhD Candidate in Environmental Microbiology / PhD Candidate in Environmental Microbiologess

PhD Position in Environmental Microbiology

100% | Zurich | Fixed-term

The Environmental Microbiology group led by Prof. Marie Schölmerich at the Department of Environmental Systems Science, ETH Zurich, invites applications for a fully funded PhD position.

Our group delves into the captivating realm of anaerobic microbiology—from the global scale to the microscopic. We investigate microorganisms that utilize ancient metabolic pathways to convert the greenhouse gases carbon dioxide and methane. By employing techniques from metagenomics, classical microbiology, and biochemistry, we examine their influence on biogeochemical cycles and unveil the molecular mechanisms propelling these processes. Our long-term goal is to understand fundamental environmental principles and inspire sustainable technologies.

This is a full-time position (100%), starting in spring 2026 or upon mutual agreement.

Job Description

The PhD candidate will conduct research in re-wetted peatlands to characterize changes in microbial communities and the underlying molecular mechanisms. The project encompasses fieldwork, metagenomic and metatranscriptomic analyses, microcosm experiments, and isolation experiments.
