Doctoral Position in Mechanics of Frictional Particle Suspensions ETH Zürich in Switzerland

Doctoral Position in Mechanics of Frictional Particle Suspensions at ETH Zurich’s Professorship of Solid Mechanics (SMEC), Institute for Building Materials.

This PhD project explores how microscopic frictional interactions between particles govern the macroscopic flow and rheological response of dense, concentrated suspensions. The work sits at the intersection of mechanics, applied physics, computational science, and materials research, and aims to connect particle-scale processes such as sliding and rolling friction, particle geometry, and contact mechanics with emergent suspension behavior across scales.

The successful doctoral researcher will undertake a computational and theoretical study using physics-based models and particle-based simulations, including coarse-grained molecular dynamics. A key part of the project is rigorous verification and validation against experimental datasets provided in collaboration with researchers from the ETH Department of Materials. The role includes analyzing simulation data to identify the mechanisms controlling suspension response and working closely with experimental partners to help interpret observations and refine the modeling framework.

The broader research environment at SMEC is highly interdisciplinary and international, with projects spanning particle systems, architected and interlocked materials, fragility in collagen, earthquake mechanics, soft fracture, and failure processes in concrete. The common theme is understanding why complex materials fail and developing predictive tools for mechanical failure. This PhD position contributes to that mission by addressing the mechanics of frictional particle suspensions, a topic relevant to rheology, granular and colloidal matter, and computational mechanics.

Applicants should have an MSc degree in mechanics, physics, civil/mechanical/aerospace/bio-engineering, materials science, or a related discipline, together with a strong background in mechanics, applied physics, computational mechanics, or scientific computing. Experience with scientific coding, Python, version control, and quantitative comparison against reference data is important. Fluency in English is required, and candidates should be curious, self-motivated, collaborative, and comfortable working in a team environment. Prior exposure to colloidal suspensions, rheology, or coarse-grained molecular dynamics is welcome but not mandatory.

The position is offered by ETH Zurich, one of the world’s leading science and technology universities, and provides a supportive, dynamic, and international research setting. ETH highlights professional development, sustainability, and a diverse and inclusive working culture. The start date is flexible and may be as soon as possible. Applications must be submitted via the online portal; email or postal applications are not considered.

For questions about the position, contact Prof. David Kammer at [email protected] (no applications). Required application materials include a CV, transcript/list of courses, a brief project statement, and contact details for two references.
