About this position
NTNU is offering a PhD Candidate position in Sustainable and Cement-Free Marine Materials at the Department of Manufacturing and Civil Engineering in Gjøvik. The project is positioned within an international and interdisciplinary research environment focused on sustainable blue economy innovation and low-carbon material solutions for marine applications.
The PhD project, HAPMarine, addresses the need for alternatives to carbon-intensive, concrete-based marine infrastructure. The research aims to upcycle calcium-rich waste streams from aquaculture shells and demolition concrete into new bioreceptive, low-carbon, and high-strength materials. The work is motivated by climate change impacts and circular-economy goals, and it connects material development with marine infrastructure and cold-water coral reef restoration.
The candidate will contribute to fundamental research on eco-friendly shell-based materials, hybrid shell–concrete geopolymer composites, and carbonation-related approaches that may improve CO₂ capture. The work includes optimisation of forming conditions, assessment of mechanical and bio-receptive performance, numerical simulation to understand processing and behaviour, and lab- and field-based testing. The project also includes leaching analysis and ecological assessment, and it is carried out in cooperation with project and industry partners.
The project involves collaboration with researchers at the University of Tokyo and the Norwegian Institute for Water Research (NIVA). The position is hosted by NTNU, whose Department of Manufacturing and Civil Engineering has expertise in sustainable solutions, modern industrial processes, and new and recycled materials. The successful candidate will join an environment that combines engineering research, sustainability, and interdisciplinary collaboration.
The immediate leader is the Research Group Leader, and the position is tied to doctoral education and coursework during the early period of employment.

What's required
Applicants must hold a relevant Master's degree in Materials Science, Chemical Engineering, Civil/Structural Engineering, Ocean Engineering or an equivalent degree, corresponding to a five-year Norwegian course with 120 credits at master's level. A strong academic background is required, with an average grade of B or better on NTNU's scale or an equally strong academic foundation if letter grades are unavailable. Candidates must meet the admission requirements for the Faculty's Doctoral Programme and have excellent written and oral English skills. Theory and experimental background in building materials such as concrete or geopolymer is required. Preferred qualifications include experience publishing in SCI journals, advanced material characterization (XRD, SEM, FTIR, MIP), numerical modelling (COMSOL/ANSYS), and background in green/bio-concrete or waste valorization.
How to apply
Apply online through the Jobbnorge application portal. Submit the application in English with CV, certificates, transcripts, diplomas, thesis copy, a 2-page project proposal, three referees, and relevant publications or research work. If applicable, include documentation of foreign degrees and NOKUT assessment.
