PhD Position: Modeling Friction in Colloidal Suspensions

100%, Zurich, Fixed-term

At the Professorship of Solid Mechanics (SMEC) in the Institute for Building Materials at ETH Zurich, we strive to understand how materials deform, degrade, break, and ultimately fail. Our research is fueled by a curiosity to explore the physical mechanisms behind material failure and aims to translate this understanding into the development of more reliable and resilient materials and structures. By integrating numerical modeling, laboratory experiments, and theoretical analyses, we aim to connect microscopic processes with the macroscopic behavior of both engineering and natural systems, as well as develop predictive tools for mechanical failure.

Our team is diverse and interdisciplinary, comprising researchers from various fields, including materials science, mechanics, and applied physics. We address a wide range of topics such as the mechanics of particle systems (colloidal and granular), architected materials, the fragility mechanics of collagen, seismic activity, fracture of soft materials, and modeling failure in multiphysical processes, including corrosion-driven degradation in concrete. What unifies these efforts is a shared curiosity regarding the failure of complex materials and a commitment to advancing our understanding through innovative concepts, experiments, and models.

We are seeking a motivated, innovative PhD student with a background in computational mechanics to engage in a project focused on the mechanics of colloidal systems. The PhD candidate will collaborate with partners from the ETH Department of Materials to investigate the roles of sliding and rolling friction, and their interplay, in the rheological properties of colloidal suspensions.

Job Description

• You will conduct computational and theoretical investigations of the influence of inter-particle friction on the rheology of concentrated suspensions.
• Your work will involve the application of physics-based models that bridge behavior across scales, from single colloidal particle geometries to the macroscopic suspension response.
• Responsibilities include implementing coarse-grained molecular dynamics simulations and performing thorough verification and validation using datasets provided by collaborators.
• You will work closely with experimental researchers on the project, providing modeling insights and aiding in the interpretation of experimental observations.
• The position offers an intellectually stimulating environment conducive to scientific growth and collaboration.

Profile

• You hold an MSc degree in mechanics, physics, (civil, mechanical, aerospace, or bio-) engineering, material science, or a related discipline.
• You possess a background in computational sciences, focusing on solid mechanics, applied physics, or a related field.
• You have experience in implementing scientific code, validating it, and verifying it against experimental data.
• You are proficient in Python programming and familiar with version control systems.
• You are curious, self-motivated, and enjoy close collaboration with experimentalists.
• You are fluent in English (both oral and written).
• You thrive in team settings, possess strong social skills, and contribute positively to group dynamics.

Workplace

The position is located within the dynamic and innovative environment of ETH Zurich, a leading university renowned for its contribution to science and technology.

We Offer

• You will join a vibrant international research group that values curiosity, rigor, and collaboration.
• Your work will have a significant impact as part of ETH Zurich, an institution committed to supporting your professional development while actively contributing to societal progress.
• We are dedicated to fostering a sustainable and climate-neutral university.
• Expect numerous benefits, including public transport season tickets, car-sharing options, access to sports facilities, childcare support, and attractive pension plans.
