PhD position: Modeling friction in colloidal suspensions ETH Zürich in Switzerland

This PhD position at ETH Zürich focuses on modeling friction in colloidal suspensions within the Professorship of Solid Mechanics (SMEC) at the Institute for Building Materials. The group investigates how materials deform, degrade, and fail, aiming to translate fundamental understanding into more reliable and resilient materials and structures. Research combines numerical modeling, laboratory experiments, and theoretical analyses to link microscopic processes with macroscopic behavior in both engineering and natural systems. The interdisciplinary team works on topics such as particle systems (colloidal and granular), architected materials, fragility in collagen, earthquake mechanics, fracture of soft materials, and multiphysical failure processes like corrosion-driven degradation of concrete.

The advertised PhD project centers on the mechanics of colloidal systems, specifically the roles of sliding and rolling friction in the rheological properties of concentrated suspensions. The candidate will conduct computational and theoretical investigations, applying physics-based models that connect single-particle geometry to the macroscopic response of suspensions. Responsibilities include implementing coarse-grained molecular dynamics simulations, rigorous verification and validation using experimental datasets, and close collaboration with experimental researchers to interpret observations and provide modeling insights.

Applicants should have an MSc in mechanics, physics, engineering (civil, mechanical, aerospace, or bio-), material science, or a related discipline, with a background in computational sciences focused on solid mechanics or applied physics. Experience in scientific programming (Python), code validation, and version control is required. Fluency in English, teamwork, and proactive communication are essential. The position offers a dynamic, international, and supportive research environment, with opportunities for professional development and societal impact. ETH Zürich is committed to diversity, sustainability, and a climate-neutral future, providing benefits such as public transport tickets, sports facilities, childcare, and attractive pension plans.

The start date is flexible, and applications are accepted exclusively through the ETH online portal. Required documents include a CV, academic transcript, a brief project statement, and contact details for two references.
