PhD Position in Environmental Microbiology (Male/Female)

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 explores the fascinating world of anaerobic microbiology—from the global to the microscopic scale. We focus on microorganisms that utilize ancient metabolic pathways to convert greenhouse gases such as carbon dioxide and methane. Through metagenomics, classical microbiology, and biochemistry, we examine their impact on biogeochemical cycles and identify the molecular mechanisms driving these processes. Our long-term goal is to deepen our understanding of fundamental environmental processes and inspire sustainable technologies.

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