PhD Stipend in purifying alternative feed and high quality food proteins from green leaves (18-23004)

At the Faculty of Engineering and Science, Department of Chemistry and Bioscience, a PhD stipend is available within the doctoral programme Biotechnology, Chemistry and Environmental Engineering. The PhD stipend is open for appointment from 1 March 2023 or as soon as possible thereafter. The position is for 3 years. The Department consists of two sections with research and teaching in Biotechnology, Chemistry, Chemical Engineering, Environmental Technology and Biology. Place of employment of the position is Section for Bioscience and Engineering in Aalborg. The section consists of 90 people of which about 30 are associate- and full professors. The section conducts internationally competitive research on various topics within Biology and Biotechnology and publishes more than 100 peer-reviewed publications annually.


The focus of the PhD project will be qualifying membrane-filtration of grass juice in order to produce functional food-grade proteins. The work will involve fine-tuning of membrane-filtration methods and assist in scaling membrane-filtration in pilot scale for producing feed- and food grade proteins. The work also involves studying and characterizing the content and composition of feed and food proteins and biorefined side-fractions using different analytical methods such as elemental analysis, qubit and other protein analytical methods. The characterization includes calculations of filtration flows and mass balances. The PhD-student shall identify consequences of changing parameters of the process steps and identify potential advantages and disadvantages of the process parameter changes regarding purity, quality, and value of the protein-rich products.

The position is a part of two research projects, Grass4Food and HQProtein, both with the overall goal to purify proteins and other valuable compounds from grass juice with high yield and to analyze the biorefined fractions with analytical methods. The work will be at Aalborg University, in collaboration with University of Copenhagen, and several companies.

Applicants must have a Master of Science (MSc.) degree in Biotechnology, Chemical Engineering, or equivalent educations. The candidate should have relevant experience with green biorefining, membrane filtration, and relevant analytical techniques. As the position is part of research projects, the candidate should also show good interpersonal and communication skills and team spirit to solve the problems together with the different stakeholders.

The application must contain:

  • Cover letter of 1-2 pages describing the motivation for applying and an account of the applicant’s background in relation to the announced position
  • Project description, which is required for technical reasons – in this case, where you apply for a specific project, you may upload a copy of the project description above
  • CV
  • Diploma and transcripts of records
  • Other relevant information.

All interested candidates are encouraged to apply, regardless of their personal background. We value diversity and see it as a strength.

For further information about the scientific aspects of the stipend, please contact Associate Professor Mette Lübeck, Department of Chemistry and Bioscience, phone: 99402590, email: Department of Chemistry and Bioscience provides cutting-edge research and teaching in biotechnology, biology, environmental science, chemistry and chemical engineering. Our research solves important topics for the benefit of society, and through research-based teaching, we educate independent, collaborative and solution-oriented bachelors, graduates and PhDs.

We are a dynamic workplace with high professionalism and efficiency, a good working environment and with a focus on work-life balance. We strive for a culture with collaboration that promotes openness and curiosity towards new initiatives and ideas and with a constructive approach to problem solving. As an employee at the department, you will be part of an international research environment, with a focus on innovation, knowledge sharing and excellency as well as interdisciplinary collaborations.

At the department, we have high-profile research groups and individual researchers who deliver world-class applied and basic scientific research with a mission-driven approach, and who contribute to the development of new technologies, methods, and new basic insights within natural science and engineering. The department is divided into two sections: Section for Bioscience and Engineering and Section for Chemical Science and Engineering, as well as one administration. Both sections have activities on both Aalborg and Esbjerg campuses. The day-to-day management is handled by the head of department, the deputy heads of research and education, and the head of the secretariat in collaboration with section leaders.

PhD stipends are allocated to individuals who hold a Master’s degree. PhD stipends are normally for a period of 3 years. It is a prerequisite for allocation of the stipend that the candidate will be enrolled as a PhD student at the Doctoral School of Engineering and Science in accordance with the regulations of Ministerial Order No. 1039 of August 27, 2013 on the PhD Programme at the Universities and Certain Higher Artistic Educational Institutions. According to the Ministerial Order, the progress of the PhD student shall be assessed at regular points in time.

Shortlisting will be applied. This means that subsequent to the deadline for applications the head of department supported by the chair of the assessment committee will select candidates for assessment. All applicants will be informed whether they will be assessed or not.
