Postdoctoral Research Fellow - Terahertz Time-Domain Spectroscopy for Plastic Classification

**Postdoctoral Researcher - Terahertz Time-Domain Spectroscopy for Plastic Sorting** Are you interested in optical characterization and eager to contribute to groundbreaking research in Terahertz Time-Domain Spectroscopy for the plastic sorting industry? The Department of Electrical and Computer Engineering at Aarhus University invites you to apply for an exciting 2-year postdoctoral position bridging research with industrial implementation and innovation. **Position Details** This is a 2-year position starting May 1st, 2026, or as soon as possible thereafter. **Role Overview** We seek a motivated researcher with a versatile profile to join our project "Terahertz Time-Domain Spectroscopy for Plastic Type Discrimination." You will address several scientific and technical challenges, including: • Design and implementation of a new THz-TDS system for plastic discrimination and sorting in industrial settings • Testing and benchmarking the system regarding experimental geometry, operational speed, and robustness against noise factors • Advanced data analysis to translate THz signals into optical material properties such as refractive index and absorption coefficient • Development of machine learning algorithms for material classification • Exploration of technological business models in collaboration with our in-house innovation hub **Your Profile** The ideal candidate should hold a PhD in Physics, Photonics, Electrical Engineering, or a related field, and demonstrate: • Experience with optical spectroscopy, ideally with terahertz technology • Proficiency in hardware control using Matlab, Python, or similar tools • Experience with machine learning algorithms and classification (preferred) • Hands-on experience in building experimental setups and hardware implementation **Additional Requirements** • Provide a statement outlining future research interests and expectations • Possess strong collaboration and communication skills • Demonstrate excellent command of English, both spoken and written • Ability to work independently on research questions and manage laboratory challenges • Capability to supervise students and contribute to a supportive research environment **About Our Team** You will join the Terahertz Photonics Group within the Department of Electrical & Computer Engineering at Aarhus University. Our research focuses on terahertz science and technology, including materials characterization of polymers, semiconductors, solar cell materials, and more. We offer access to well-equipped laboratories featuring both custom-built and commercial terahertz time-domain spectroscopy (THz-TDS) systems. Our group consists of researchers and students at all academic levels, providing an environment that supports studies ranging from applied research to fundamental scientific questions. **What We Offer** The successful candidate will have a unique opportunity to join a multidisciplinary team dedicated to addressing one of today's most pressing challenges: plastic recycling. This project combines scientific exploration with technological innovation, offering the chance to contribute to both cutting-edge research and practical solutions. Additionally, you may engage with business-oriented perspectives through collaboration with our innovation hub. **Location** Department of Electrical and Computer Engineering, Aarhus University, Finlandsgade 22, 8200 Aarhus N, Denmark **Application Deadline** January 31st, 2026 **Application Requirements** Applications must be in English and include: • Curriculum vitae • Degree certificate • Complete list of publications • Statement of future research plans and research activities • Teaching portfolio and verified information on previous teaching experience (if any) **Selection Process** We use a shortlisting process where the head of department selects candidates for evaluation with assistance from the assessment committee. All applicants will be notified whether their applications proceed to expert assessment. **Employment Terms** Appointment follows the collective labor agreement between the Danish Ministry of Taxation and the Danish Confederation of Professional Associations. Salary depends on seniority as agreed between these organizations. **Our Commitment** Aarhus University strives to be an attractive and inspiring workplace fostering a culture where each individual can thrive, achieve, and develop. We view equality and diversity as assets and welcome all applicants. We offer comprehensive services for international researchers and families, including relocation services, career counseling, and a Junior Researcher Development Programme. Research activities will be evaluated relative to actual research time, and we encourage applicants to specify periods of leave without research activities for fair evaluation of scientific productivity.
