Civil Engineering and Geosciences

The Faculty of Civil Engineering and Geosciences of Delft University of Technology (TU Delft) provides leading international research and education, with innovation and sustainability as central themes. Research and education are closely interwoven and address societal challenges. The Faculty consists of the departments of Transport and Planning, Structural Engineering, Geoscience and Engineering, Water Management, Hydraulic Engineering, and Geoscience and Remote Sensing.

The Department of Structural Engineering provides education and conducts research in the area of civil infrastructure and buildings. The department’s approach is based on science/fundamentals (mechanics and material science), deepened by engineering (concrete, steel, composite, timber, road and railway structures) and broadened by design (integral design, construction design, zero-material design and design-build). The department provides the basic education in the BSc civil engineering programme and three MSc programmes.

The Resources and Recycling Chair is an extremely productive research group with strong links to the minerals processing and recycling industry. The chair’s ambition is to create breakthroughs in recycling by applying fundamental science to innovative processes and implementing them in collaborations with industry. The ongoing research projects combine theoretical insights and modelling with experiments in the group’s laboratory and in pilot plants.

Job description

The challenge:
The H2020 project HISER involves 25 partners with researchers from universities, research centres and industries, working closely together to reach a common goal: to develop and demonstrate a series of novel and cost-effective solutions for making new raw materials from construction and demolition waste (CDW). Delft University of Technology has developed Laser-Induced Breakdown Spectroscopy (LIBS) for continuously assessing the quality of the recycled mineral products to the level of a laboratory prototype. In HISER, we aim to create an industrial technology for determining the type of EOL concrete and detecting contaminant particles at very low concentrations in recycled mineral flows.
Research in the Resources and Recycling group has a reputation for moving innovative physics into industrial reality, resulting in six spin-out companies to date. The project offers the opportunity for a new post-doc to join our team and work together with innovative industries involved in the HISER project.

The position:
The candidate’s research will be aimed at developing a prototype and complementary data analysis algorithm for online LIBS-based material identification. This research builds on preceding successful PhD research in our group and will form a critical step to achieving industrial adaptation. To this end, the candidate should provide the know-how and technology to allow for continuous and fast sensor measurements, which is required for on-site materials quality assessment and evaluation of performance of large-scale concrete recycling processes.


Our group seeks an enthusiastic post-doc with a background in LIBS or a neighbouring field. The research involves building a set-up, performing experiments in the lab as well as in the field, and real-time data collection and analysis. The experimental part includes signal processing and mechanical process control. You are interested in the specific fields of physics to be studied and have a good comprehension of English, both spoken and written. Candidates should have an affinity for innovation and working in multidisciplinary teams.

Conditions of employment

The TU Delft offers an attractive, customisable compensation and benefits package, including a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers day care, before- and after-school care and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
