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

Join Our Research Team

We are searching for two highly motivated individuals to become part of an interdisciplinary team focused on the biogeochemical cycles of trace elements at ETH Zurich and Eawag, the Swiss Federal Institute of Aquatic Science and Technology. Our aim is to enhance the understanding and prediction of the environmental distributions of health-impacting trace elements, helping to mitigate future health hazards.

Project Overview

The focus of our research revolves around a new Swiss National Science Foundation (SNSF) funded project, which seeks to deepen our knowledge of the essential micronutrient selenium (Se). Specifically, we aim to elucidate the atmospheric movement of selenium—from emissions to deposition—utilizing field sampling, laboratory analyses, and advanced computational modeling. A comparative analysis with sulfur (S) will also be undertaken due to the chemical similarities between these nutrients.

Details of the Projects

• Project A: This project involves designing and executing field sampling campaigns in diverse environments, including urban, mountainous, and marine settings. Responsibilities include collecting both wet (rain, hail, snow) and dry (aerosol) deposition samples, conducting lab analyses to determine the elemental composition, and developing hypotheses about atmospheric processes affecting selenium cycling.
• Project B: This project aims to expand our global selenium cycling model, which is part of the ICON-ART modeling system. Tasks involve understanding environmental pathways of selenium, utilizing statistical methods for hypothesis testing, and producing atmospheric Se input maps to predict changes in deposition patterns due to future climate and emission scenarios.

Both projects will allow for exploration of innovative ideas and require collaboration with various partners. Publication in peer-reviewed journals and presentations at international conferences are integral to the role, along with organizing regular team meetings and contributing to teaching activities at ETH Zurich.

Candidate Profile

• For Project A: Candidates should possess an MSc in environmental chemistry, geochemistry, or related fields, exhibit enthusiasm for field research, and have strong capabilities in laboratory analysis, ideally with experience in ICP-MS techniques.
• For Project B: Candidates should hold an MSc in atmospheric or climate sciences, environmental or Earth sciences, or closely related disciplines, with strong programming skills in languages such as Fortran, C, R, or Python. Previous experience in process-based modeling is advantageous.

Fluency in English, strong communication skills, and a collaborative spirit are essential for both projects. We encourage self-driven individuals with critical thinking skills to apply.

What We Offer

• Training opportunities with leading experts in relevant fields
• Support programs and networking opportunities, including access to international conferences
• An interdisciplinary research group that combines expertise across various domains
• A supportive working environment that prioritizes group well-being
• Flexible working hours and options for remote work to promote a healthy work-life balance
• A competitive PhD salary in alignment with ETH standards, with funding assured for four years

Commitment to Diversity

We highly value diversity and strive to create an inclusive culture at ETH Zurich. Our environment supports equality of opportunity, where every individual’s rights and dignity are respected, allowing everyone to grow and succeed.
