PhD Candidate in 3-D Geological Modelling of the Eastern Penninics / PhD Candidate in 3-D Geological Modelling of the Eastern Penninics

PhD Position: 3-D Geological Modelling of the Eastern Penninics

100%, Zurich, fixed-term

The Structural Geology and Tectonics group focuses on the rapidly deforming zones that define Earth's tectonic plate boundaries and contribute to many of the planet's geohazards. We are excited to announce a new PhD position open for 3D geologic modeling of the Eastern Penninics in the Swiss Alps.

Project Background

The eastern Penninic nappe stack of the Swiss Alps preserves a complex record of subduction, accretion, nappe emplacement, metamorphism, and exhumation. Its major tectonic boundaries provide an exceptional natural laboratory for reconstructing the three-dimensional architecture of the Alps and for testing how inherited geometry, lithology, and deformation history influence crustal-scale structures.

As part of the swisstopo swissAlps3D project, this PhD project will utilize 3-D geological modeling as a core tool to reconstruct the subsurface structure of the eastern Penninics in Switzerland. Over four years, the selected candidate will build a high-quality, 3-D geological model by integrating geological maps, structural data, cross-sections, tunnel and borehole information, geophysical constraints, and published metamorphic and thermochronological datasets.

The project involves collaboration with neighboring modeling efforts, along with targeted field-based work on selected tectonic boundaries within the model area. These efforts aim to link regional-scale 3-D architecture with variations in lithology, deformation fabrics, metamorphic history, and fluid-related features along major crustal interfaces. In the later stages of the project, the candidate will utilize the attributed 3-D model to develop a process-oriented representation of an ancient subduction-interface system and explore how its geometry and internal heterogeneity may have influenced segmentation, strain localization, and slip behavior.

This project, funded by swisstopo, will be hosted in the Structural Geology & Tectonics Group at ETH Zurich under the supervision of Prof. Whitney Behr, in collaboration with swisstopo and Dr. Lukas Nibourel from the Georesources Switzerland Group at ETH Zurich.

Job Description

• Compile and harmonize regional geological datasets, including maps, cross-sections, structural measurements, tunnel and borehole data, and published constraints.
• Construct a comprehensive 3-D geological model of the eastern Penninic nappe stack, with thorough documentation of assumptions and uncertainties.
• Develop a consistent structural scheme and unit legend in coordination with swisstopo and neighboring modeling efforts.
• Conduct targeted fieldwork to resolve key geometric uncertainties and collect structural observations.
• Utilize the 3-D model to investigate the architecture, continuity, and tectonic significance of major crustal boundaries.
• Prepare model documentation, reports, manuscripts, and conference presentations.

Profile

• MSc in Earth Sciences/Geology or a related field.
• Strong interest in field geology, structural geology, tectonics, and/or 3-D geological modeling.
• Experience with geological mapping, GIS, cross-section construction, or 3-D modeling software is an advantage.
• Willingness to conduct fieldwork in Alpine terrain.
• Strong proficiency in English; German is beneficial but not required.
• Collaborative, organized, independent, and meticulous with complex datasets and uncertainties.

Workplace

The position will be based within the vibrant and research-driven environment at ETH Zurich, promoting an atmosphere of innovation and collaboration.

We Offer

• A friendly, dynamic, and interdisciplinary environment within the Structural Geology & Tectonics Group (led by Prof. Whitney Behr).
• Access to a wide range of experimental and analytical facilities at ETH Zentrum and ScopeM (Hönggerberg).
• Competitive ETH salary and benefits, with the PhD position funded for four years.
