Two PhD positions in atmospheric selenium research: field & lab analyses and process-based modeling

Join Our Innovative Research Team

We invite two exceptional and driven PhD candidates to join the Inorganic Environmental Geochemistry group at ETH Zurich and Eawag, the Swiss Federal Institute of Aquatic Science and Technology. As part of an interdisciplinary team, you will contribute to the study of biogeochemical cycles of trace elements, with a focus on understanding and predicting environmental distributions of health-impacting trace elements.

Project Background

These positions are part of a Swiss National Science Foundation (SNSF) funded project aimed at enhancing our understanding of selenium (Se) cycling through the atmosphere. The project encompasses field sampling, lab analyses, and computational atmospheric modeling to explore the atmospheric role in the global biogeochemical cycle of Se, alongside its comparison to sulfur (S).

Opportunities Available

• Project A: In this role, you will design and conduct field sampling campaigns across diverse environments, collecting wet and dry deposition samples. You will perform lab analyses to determine elemental composition and speciation, interpreting data to develop scientific hypotheses concerning atmospheric processes affecting selenium and other trace elements.
• Project B: This position focuses on extending a global selenium cycling model within the ICON-ART modeling system. You will investigate selenium’s environmental pathways, from emissions to deposition. Employing statistical methods for hypothesis testing, you will create maps of atmospheric Se inputs and predict future deposition patterns while validating your results with both existing and new data.

Your Profile

For Project A: Candidates should possess a MSc degree in environmental chemistry, geochemistry, or a related field. A strong interest in chemical analyses and experience with ICP-MS or similar techniques are advantageous. Enthusiasm for fieldwork in varying seasonal conditions is essential.

For Project B: Applicants should hold a MSc degree in atmospheric, climate, or computational sciences. Proficiency in programming languages such as Fortran, C, R, or Python is required, with prior experience in process-based modeling being a plus.

Fluency in English, both written and spoken, is essential for all candidates. The ideal individuals are self-motivated, critical thinkers, and eager to collaborate within our diverse team.

What We Offer

• Training with leading experts in chemical analytics, modeling, and biogeochemical cycles.
• Support programs and networking opportunities, including attendance at international conferences.
• A collaborative research group combining expertise in biogeochemical analytics and modeling.
• A supportive environment that prioritizes well-being and promotes a healthy work-life balance.
• A competitive PhD salary aligned with ETH standards, with secure funding for 4 years.

Commitment to Diversity and Sustainability

ETH Zurich fosters an inclusive culture that values diversity and equality of opportunity. We strive to create a working and learning environment that respects the rights and dignity of all staff and students. Sustainability remains a core value, and we continuously work towards a climate-neutral future.
