PhD Position in Deformation & Microstructures of Eclogites ETH Zürich in Switzerland

The Structural Geology and Tectonics Group at ETH Zürich, led by Professor Whitney Behr, is offering a 4-year PhD position focused on the deformation and microstructures of eclogites, with a particular emphasis on subduction interface rheology. Eclogite, a dense, high-pressure metamorphic rock, plays a significant role in the strength and behavior of subduction zones and the deep lower crust, influencing tectonic processes such as plate coupling, slab pull, and crustal foundering. Despite its importance, the strength of eclogite under diffusion creep—a weak, grain-size-sensitive deformation mechanism—has not been experimentally quantified. This project aims to provide the first high-pressure/high-temperature calibration of eclogite diffusion-creep behavior and validate these findings against natural samples from Norway’s Western Gneiss Region using both field and microstructural observations.

The successful PhD candidate will conduct shear and deformation experiments under diffusion-creep conditions, assist with high-pressure and high-temperature runs, and perform detailed microstructural and petrological analyses using techniques such as EBSD, EDS, microprobe, FTIR, and micro-CT. The project also includes participation in field campaigns in Norway, where the student will collect and analyze natural samples, linking laboratory results to natural structures. The position offers a dynamic and interdisciplinary research environment within the Structural Geology & Tectonics Group, access to state-of-the-art experimental and analytical facilities at ETH Zentrum and ScopeM, and a competitive salary and benefits package.

ETH Zürich is committed to diversity, sustainability, and providing an inclusive environment for all staff and students. Applicants should have an MSc in Earth Sciences, Geology, or a related field, with a strong background in structural geology, petrology, or rock mechanics.

Solid English skills, enthusiasm for experimental and microstructural work, and the ability to work collaboratively and participate in fieldwork are essential. To apply, candidates must submit their application online through the ETH Zurich portal, including a CV, a statement of research interests, proof of MSc degree and transcripts, and contact information for two referees. Applications via email or postal services will not be considered.

For further information, applicants may contact Mrs. Perscheng Assef (no applications via email).
