Vacancy - PhD scholarship in bio-cemented mycelium composites

We are looking for a full-time doctoral candidate for an interdisciplinary research project on the development of bio-cemented mycelium-based composites. The project responds to the growing need for sustainable, circular and bio-based materials for the construction sector. Mycelium-based composites, consisting of fungal hyphae that bind natural lignocellulosic fibres, offer promising properties such as low weight, thermal insulation, acoustic absorption and biodegradability. However, their use is currently mainly limited to non-structural applications, as their mechanical properties remain insufficient for load-bearing or semi-structural use.

This PhD project investigates how the mechanical properties of mycelium-based composites can be improved through bio-cementation. The central hypothesis is that microbial mineralisation can lead to the formation of calcium-based crystals in or on the mycelium network, creating a reinforcing matrix that increases the strength and stiffness of the composite material. 

The doctoral candidate will work within an interdisciplinary VUB research team focusing on mycelium-based materials, microbiology and sustainable construction materials, which operates on the interface between the Architectural Engineering Research Group and the Research Group of Microbiology (Department of Bioengineering Sciences). The project requires a combination of microbiological experimentation, material production, chemical and microscopic characterisation and mechanical testing. The candidate will develop protocols for the growth and bio-cementation of mycelium-based composites, study the influence of growth conditions and process parameters and evaluate the resulting materials in terms of their mechanical performance.

The doctoral candidate will also, to a limited extend, contribute to teaching activities within the Architectural Engineering department. The candidate will guide students in exercise sessions, practicals, and/or student projects. The specific teaching assignment will be determined annually in consultation with the candidate.
