Are you passionate about sustainable innovation, food safety, and creating real-world impact through cutting-edge materials science? Do you want to help design the future of food packaging, one that’s safer, smarter, and more environmentally responsible?

We are looking for a highly motivated PhD student to join our dynamic, interdisciplinary research team. By joining us, you'll gain expertise in bio-based materials, packaging technologies, and food safety evaluation while contributing to one of the most urgent sustainability challenges: reducing plastic waste without compromising food quality or safety. You’ll also build valuable connections with industry and academia. The project fosters strategic interdisciplinary collaboration across DTU Food, and DTU Sustain to holistically develop and evaluate sustainable food packaging solutions that integrate material innovation, production systems, and microbiological safety for high-impact societal and scientific outcomes.

Responsibilities and qualifications
Your overall focus will be to develop and evaluate bio-based circular packaging materials that improve food safety, reduce waste, and support circular value chains. The work includes formulation, characterization, and performance testing of packaging systems in food applications. This PhD project aims to develop, characterize, and validate bio-based food packaging materials derived from agricultural and industrial side streams, and expects to address critical gaps in the development, feasibility, and regulation of biomass-based packaging. Its multidisciplinary approach will deliver science-based evidence essential for guiding national policy and shaping future regulatory frameworks in this rapidly evolving area.

Your primary tasks will be to:

• Design and develop bio-based and biodegradable packaging materials
• Test food-contact safety, microbial barrier performance, and shelf-life impact
• Assess the environmental performance of the developed product through its full life cycle with LCA
• Collaborate with engaging stakeholders: (e.g. industry stakeholders, academic partners, policymakers)
• Disseminate research results through peer-reviewed publications, conferences, and workshops
• Contribute to the supervision of MSc and BSc students
• Complete relevant PhD courses, academic training at DTU
• Engage teaching activities related to the Packaging

We are looking for candidates who have:

• A two-year Master’s degree (120 ECTS points) or equivalent in Food Science, Materials Science and Engineering, Packaging Technology, or a related field
• Documented experience with food and bio-based materials chemistry (particularly for packaging), and analytical techniques
• Experience in packaging processing technologies (e.g. extrusion, Injection, compression molding, others)
• Familiarity with relevant methods such as Microscopy (SEM, AFM), Spectroscopy (e.g. FTIR, Raman), and antimicrobial assays, and/or other relevant methods for characterizing packaging materials and foods. Previous knowledge of LCA is also a plus.
• Strong experimental and problem-solving skills
• A proactive mindset and the ability to work independently and in teams
• Excellent communication skills in English (written and spoken)

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment  
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education . 

Assessment
The assessment of applicants will be made by an academic committee composed of supervisors from the relevant departments. Emphasis will be placed on the applicant’s academic qualifications, motivation, and potential for completing a high-quality PhD project.
