Are you interested in optical terahertz spectroscopy and can you contribute to the development of the project “Industrial recycling of post-consumer plastics – inline analysis, documentation and sorting (RePlast)”? Then the Department of Electrical & Computer Engineering invites you to apply for a 2-year postdoc position.

Expected start date and duration of employment

This is a 2–year position from 1st of October, 2022 or as soon possible.

Job description

During the RePlast project an optical terahertz system is developed to work along with a hyperspectral camera to identify different types of plastics to be sorted on a conveyer belt in an industrial facility. Ideally, this will result in a faster process and higher purity of recycled plastic components.

You will be contributing to the implementation a terahertz system to an inline optical detection platform capable of discriminating different types of plastics. This includes both the materials characterization of polymers with different types of additives and fillers, the instrumentation related to the use of a terahertz system in an industrial setting, and the data analysis related to the discrimination of the plastics.

Your profile

The candidate is expected to hold a PhD in Physics, Photonics, Electrical Engineering or similar and have
  • Experience with optical spectroscopy and ideally terahertz technology. 
  • Experience with hardware control using Matlab, Labview, Python or similar. Experience with machine learning algorithms and classification is an advantage.
  • Extended experience with experimental work. 
Furthermore, applicants are expected to: 
  • Make a statement on future research expectations including area of interest. 
  • Have strong cooperation and communication skills. 
  • Have very good command of the English language, both spoken and written. 
  • Be able to work independent on research questions and deal with practical problems related to our laboratory facilities etc.
  • Capable of assisting students in their research projects and contribute to a constructive atmosphere within our research group.

Who we are

You will be a part of the Terahertz Photonics Group located in the Department of Electrical & Computer Engineering at Aarhus University. We are specialized within terahertz science and technology including using terahertz systems for materials characterization of polymers, semiconductors, solar cell materials etc. We have a newly established laboratory facility both consisting of custom and commercial terahertz time-domain systems available project. Our group consist of researchers and students at all academic levels giving a young and dynamic work culture, with room for studies of both applied and fundamental scientific questions. Within the RePlast project, we work in close collaboration with our project partners in the Danish industry and the Department of Bio- and Chemical Engineering to fulfill the overall goals of the project.

What we offer

The successful candidate a unique opportunity to be a part of a multidisciplinary team working towards solving today’s challenges in plastic recycling, where knowledge can be exchanged within our industrial and academic project partners working with complementary skills and knowledge.

Place of work and area of employment

The place of work is Department of Electrical and Computer Engineering, Aarhus University, Finlandsgade 22, 8200 Aarhus N, and the area of employment is Aarhus University with related departments.
