Studierende finden an der ETH Zürich ein Umfeld, das eigenständiges Denken fördert, Forschende ein Klima, das zu Spitzenleistungen inspiriert.
The group in the is seeking a PhD student to study how the global sulfur cycle regulates Earth’s long-term habitability. Our group is committed to investigating the processes that drive global environmental changes over human to geologic timescales. We effectively integrate field-based sample collection with lab-based geochemical measurements and numerical models. Combined, our work intersects several traditional Earth-science fields to holistically study the drivers and impacts of global biogeochemical cycles throughout Earth’s history.
This position is part of the ERC-funded project “Respires: Reconstructing the Effect of Sulfide Respiration on Global Redox State”. The project strives to resolve the controls on—and reconstruct past changes in—pyrite mineral weathering, a major process that governs atmospheric oxygen and carbon dioxide levels. Specifically, we will study this process using innovative “triple” oxygen isotope compositions of sulfate—the main product of pyrite weathering—from a suite of global rivers. We will determine how these signals relate to geologic and climatic factors such as bedrock type, erosion rate, and precipitation amount. Our ultimate goal is to better interpret how pyrite weathering has changed in the geologic past, including its role in the evolution of life and the rise of atmospheric oxygen.
You will be responsible for the modern global weathering aspects, with the specific duties:
This position is integral to the “sulfur-cycle” research team—which includes 2 PhD students and 1 postdoctoral researcher—within the larger SEE group. You will therefore lead these tasks but will be supported by the PI and postdoc. This multidisciplinary team offers the opportunity to learn, develop, and apply scientific skills beyond traditional isotope geochemistry!
Required experience, skills, and characteristics:
Desirable criteria:
We offer excellent, inclusive working conditions and an internationally competitive salary (paid according to ). Our laboratories are located in downtown Zurich and the working language is English. The start date will ideally be between 1 September and 1 November 2022. The position is temporary for 4 years.
