KU Leuven invites applications for a full-time PhD position focused on moisture transport in heritage brick masonry structures, based in the Building Physics and Sustainable Design section of the Department of Civil Engineering. This research group is renowned for its work across multiple scales, from material properties to building occupants’ behavior, and is now launching a new research line on the preventive conservation of cultural heritage monuments, particularly in the context of climate change and humidity challenges.

The PhD project aims to advance the understanding and numerical modeling of moisture transfer across brick-mortar and mortar-mortar interfaces in historic masonry. Heritage buildings, often constructed with uninsulated load-bearing masonry walls, face significant challenges in moisture control, which is critical for their preservation and energy efficiency. The research will address the complex behavior of moisture transfer in masonry, which can differ from the sum of its individual materials due to contact phenomena. The project will involve developing novel measurement techniques to determine the hygric properties of cured mortars, quantifying moisture-dependent interface resistance under transient conditions, and creating guidelines for implementing these findings in numerical simulations.

The successful candidate will be supervised by Prof. Evy Vereecken (KU Leuven and Royal Institute for Cultural Heritage) and co-supervised by Prof. Staf Roels (KU Leuven). In addition to research, the PhD student will publish in academic journals, present at conferences, participate in doctoral training at the Arenberg Doctoral School, and assist with teaching and supervision within the Department of Civil Engineering and the Master of Conservation of Monuments and Sites.

Applicants should hold a Master’s degree in Engineering Science (Civil Engineering, Architecture, or equivalent) with a strong background in building physics and at least distinction in their studies. Candidates should be proactive, creative, capable of independent and team work, and interested in both experimental and numerical research related to built heritage conservation. Excellent English proficiency is required, and candidates must be willing to relocate to Belgium if not already resident. The position is a full-time PhD scholarship for one year, extendable to four years upon positive evaluation, with salary and benefits according to KU Leuven standards. The anticipated start date is April 2026, with flexibility based on candidate availability.

KU Leuven offers a stimulating academic environment, extensive training opportunities, and access to a broad national and international network. The university is committed to diversity, inclusion, and equal opportunity. For further information, contact Prof. Evy Vereecken or Prof. Staf Roels. Applications must be submitted online by December 17, 2025, including a cover letter, CV, transcripts, sample of research, and referee contact details.
