PhD position on Bio-Cemented Mineral Composites for Building Applications

PhD position on Bio-Cemented Mineral Composites for Building Applications (ref. BAP-2026-561) Last modified: 31/08/26 The PhD will be jointly supervised by Prof. Özlem Cizer and Prof. Ruben Snellings at KU Leuven. The Sustainable Construction Materials for Durable Structures group of prof. Cizer contributes expertise in carbonation and bio-cementation mechanisms, porous-material microstructure and performance assessment. The Applied Mineralogy group of prof. Snellings contributes expertise in low-carbon mineral binders, precursor reactivity, mineral carbonation and advanced mineralogical characterization. The researcher will be embedded in a broader interdisciplinary consortium and collaborate with teams in synthetic microbiology, microstructure-scale modelling and architectural biofabrication. The participating laboratories provide advanced facilities for mineral processing, material characterization, and cement and concrete testing. Unit website Project The construction industry is increasingly exploring biological routes for producing more sustainable materials. However, current approaches often use enzymes or microorganisms as passive additives rather than as programmable components. The E.CoLith project – Bacterially Engineered Concrete Lithification aims to develop a new generation of biomineral composites by integrating synthetic microbiology, concrete chemistry, mineralogy and material engineering to develop programmable biomineral composites. You will perform research tasks in Work Package 2: Material Formulation, Bio-Fabrication & Characterization. Your task will focus on designing porous mineral scaffolds and binder-precursor systems that support controlled bacterial colonization, and calcium carbonate and silica mineralization, while achieving relevant processing, microstructural and engineering properties. The work will progress from well-defined model minerals to recycled and secondary mineral resources with the support of the supervisors and project consortium. The position includes the following responsibilities and tasks: Conduct research activities within the scope of the E.CoLith project. Collaborate closely with the other researchers in synthetic microbiology, modelling and living-material architecture. Participate actively in the Materials and Constructions group and the wider E.CoLith consortium. Complete the doctoral training programme of the KU Leuven Arenberg Doctoral School through publications, conference participation and coursework, and contribute to supervision and limited teaching activities related to the research. Profile You hold a Master’s degree with strong academic performance in Civil Engineering, Materials Engineering or Materials Science, Geology, Mineralogy, Geochemistry, Chemistry or Applied Chemistry, or a closely related discipline. Final-year Master’s students may apply if they obtain the degree before appointment. You have a strong background in at least one relevant area, such as mineral-based materials, cement chemistry, mineralogy, crystallization, porous materials, biomineralization or biofabrication. You have demonstrated research and experimental skills, for example through your Master’s thesis. Experience with one or more of the following is an asset: X-ray diffraction, thermal analysis, microscopy, spectroscopy, pore-structure characterization, geochemistry. You are interested in interdisciplinary research at the interface of materials science and microbiology and are motivated to acquire complementary expertise. Prior expertise in both microbiology and construction materials is not required. You are highly motivated, analytical, creative and careful in laboratory work. You can work independently and contribute effectively to a multidisciplinary team. You have excellent oral and written communication skills in English. You meet the admission requirements of the KU Leuven Arenberg Doctoral School: https://admin.kuleuven.be/rd/doctoraatsreglement/en/phdregulation-set Offer A full-time doctoral scholarship for four years, subject to positive evaluation, and a PhD degree in Engineering Science upon successful completion. Joint supervision by the Sustainable Construction Materials and Applied Mineralogy research groups. An interdisciplinary research environment combining materials engineering, concrete and mineral chemistry, synthetic microbiology, modelling and biofabrication. Access to advanced facilities for mineral processing, material fabrication, microbial experimentation and multiscale characterization. Opportunities for research activities and interdisciplinary training across the participating laboratories. Participation in international conferences, doctoral training, scientific publications and the wider E.CoLith research network. A stimulating and international work environment at KU Leuven, with a workplace at the Department of Civil Engineering in Heverlee (Leuven). KU Leuven benefits, including health insurance and access to university infrastructure and sports facilities. Interested?
