PhD in Material Science of Stone Conservation (Male/Female)

ETH Zurich - June 26, 2026

PhD Opening in Material Science of Stone Conservation

100%, Zurich, Fixed-Term

The Chair for Physical Chemistry of Building Materials invites applications for a PhD position focused on stone conservation, particularly on the mechanisms of contour scaling. This PhD is part of the collaborative project "Spatially Graded 3D Printing to Elucidate Contour Scaling of Building Stones". The project aims to investigate the mechanisms behind contour scaling in building stones, establish on-site monitoring methods, and test potential treatments. The selected student will collaborate with another PhD candidate employed at the Chair for Digital Building Technologies in the Department of Architecture.

Project Background

This project aims to establish and validate a novel experimental approach to studying stone deterioration by leveraging powder-bed 3D printing of stone-like materials. This technique enables the creation of spatially graded samples that mimic natural stones and their alterations due to weathering. Importantly, this can be done repetitively with systematic variations of defects, flaws, and inhomogeneities known to affect stone deterioration.

The specific stone deterioration mechanism under investigation is contour scaling, a concern primarily related to molasse sandstones commonly used in the Swiss plateau. This process results in a loss of cohesion below the exposed surface, at depths ranging from a few millimeters to several centimeters, leading to highly inhomogeneous properties that our 3D printing approach will replicate for the first time.

The 3D printing will utilize a state-of-the-art, large-scale 3D powder bed printer developed by the Chair for Digital Building Technologies, and will be advanced for this project by the other PhD student.

Job Description

  • The PhD student will utilize 3D printed stones in the unique testing facilities of the Chair for Physical Chemistry of Building Materials.
  • This research will enable the reproduction under laboratory conditions of harsh events impacting the weathering of building stones on monuments.
  • The study will be complemented by method development to facilitate rapid detection of contour scales on-site, while exploring potential measures to halt the propagation and/or formation of such scales.

Profile

  • The successful candidate should possess a keen interest, or preferably experience, in heritage conservation science.
  • A Master's degree in conservation science, material science, chemistry, chemical engineering, civil engineering, or conservation architecture is required.
  • Good experimental skills are essential.
  • A strong command of both oral and written English is necessary.
  • Conversational knowledge of German is advantageous, but a willingness to learn it is a must.
  • Excellent communication skills and a commitment to collaboration with other researchers are critical, given the project's multidisciplinary nature.

Workplace

The Chair of Physical Chemistry of Building Materials within the Institute for Building Materials offers substantial opportunities to kick-start an academic or industrial research career in cement and concrete technology, grounded in materials chemistry and rheology.

Our diverse and international team provides extensive networking opportunities through academic societies such as RILEM, industrial connections, and internal ETH collaborations. We are dedicated to fostering diversity by offering flexible working hours, remote work options, and measures that ensure our team members can excel in their roles.
