Whitney Behr

This postdoctoral position in the Structural Geology and Tectonics Group at ETH Zürich, led by Professor Whitney Behr, offers a unique opportunity to conduct experimental research on the rheology of eclogites—high-pressure metamorphic rocks that play a critical role in subduction zone dynamics and deep crustal processes. The successful candidate will lead a project funded by the Swiss National Science Foundation, aiming to deliver the first high-pressure/high-temperature calibration of eclogite diffusion-creep behavior. The research will involve designing and conducting deformation experiments using a newly installed Griggs-type apparatus capable of reaching pressures of 3 GPa or higher in the Rock Physics and Mechanics Laboratory. The postdoc will quantify the mechanical behavior of eclogite, derive flow-law parameters, and integrate microstructural data from advanced analytical techniques such as EBSD, EDS, microprobe, FTIR, and micro-CT. Complementary field sampling and microstructural comparisons will be conducted in Norway’s Western Gneiss Region to validate experimental results against natural samples. The position is for three years and includes full ETH Zürich employee benefits. Applicants should have a PhD in Earth Sciences or a closely related field, with experience in high-pressure/high-temperature rock deformation experiments and familiarity with relevant microstructural and analytical tools. The group values diversity, sustainability, and an inclusive working environment. Applications must be submitted online and should include a PhD degree, a CV (maximum three pages), and contact information for two referees. For further information about the group or the position, candidates may contact Mrs. Perscheng Assef (no applications via email). ETH Zürich is a world-leading institution in science and technology, offering a dynamic and interdisciplinary research environment in the heart of Europe.

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).

The Structural Geology and Tectonics Group at ETH Zürich, led by Professor Whitney Behr, invites applications for a 3-year postdoctoral position focused on experimental rheology of eclogites. This research aims to advance our understanding of subduction interface mechanics by quantifying the strength and deformation mechanisms of eclogite, a high-pressure metamorphic rock critical to plate tectonics and deep crustal processes. The successful candidate will design and conduct high-pressure/high-temperature deformation experiments using a Griggs-type apparatus (≥3 GPa) in the Rock Physics and Mechanics Laboratory, calibrating flow-law parameters and integrating microstructural data from EBSD/EDS, microprobe, FTIR, and micro-CT analyses. Comparative field sampling and microstructural studies will be conducted in Norway’s Western Gneiss Region to validate experimental results against natural samples. This project is funded by the Swiss National Science Foundation and offers a dynamic, interdisciplinary environment within the Structural Geology & Tectonics Group. ETH Zürich provides a 100% fixed-term position for three years, along with a comprehensive benefits package. The group values diversity, sustainability, and an inclusive culture, promoting equality of opportunity and a climate-neutral future. The postdoctoral researcher will be expected to present findings at group meetings, international conferences, and in peer-reviewed publications. Applicants should hold a PhD in Earth Sciences or a closely related field, with experience in high-pressure/high-temperature rock deformation or similar experimental methods. Familiarity with microstructural and analytical tools (EBSD/SEM, microprobe, FTIR, micro-CT) is required, as are excellent English communication skills and a collaborative working style. Motivation to link laboratory experiments with natural geological observations is essential. To apply, submit your application online via the ETH Zürich portal, including your PhD degree, a CV (maximum 3 pages), and contact information for two referees. Applications sent by email or post will not be considered. For further information about the group, visit the group website.
