Marie Schölmerich

Doctoral Position in Environmental Microbiology at ETH Zurich The Environmental Microbiology group led by Prof. Marie Schölmerich in the Department of Environmental Systems Science, ETH Zurich is recruiting for a fully funded 4-year PhD position . The project is embedded in the interdisciplinary NCCR Genesis network, which connects microbiology with geochemistry, planetary science, physics, chemistry, and origin-of-life research. This doctoral project focuses on the physiology and bioenergetics of alkaliphilic methanogenic archaea . You will investigate how methanogens grow under high-pH conditions, how they conserve energy and acquire carbon, and which signatures distinguish biologically produced methane from abiotic methane. The research combines anaerobic cultivation , physiology , and biochemistry , with relevance to the methane cycle, extreme environments, and astrobiology. Academic fields and keywords: environmental microbiology, microbiology, biology, biochemistry, environmental science, earth science, geochemistry, astrobiology, planetary science. Eligibility highlights: applicants should hold an MSc or equivalent in microbiology, environmental sciences, or a related field. Experience in anaerobic cultivation and/or protein biochemistry is an advantage. Strong curiosity, enthusiasm for experimental work, and excellent English communication skills are expected. Funding: the position is fully funded for 4 years. Application materials: cover letter, CV with publication list, diploma, transcript of records, and contact details of two references. Applications must be submitted via the official ETH Zurich online portal; applications by email or post will not be considered. Deadline: 1 December 2026. Questions regarding the position can be directed to Prof. Marie Schölmerich at [email protected].
