Do you love fermentation and food innovation? Do you want to contribute to more sustainable, resilient and just food systems? Are you interested in traditional food fermentation and would like to build innovation on traditional and ecological knowledge?

Then join us in the Fermentation Cultures group at DTU BRIGHT, where we study fermented foods as living biocultural systems at the intersection of microbial life and human culture. Combining microbiology, mycology, ecology, evolution and genomics, we investigate the origins and evolution of food microorganisms, their interactions within fermented food ecosystems, and the genetic and ecological drivers of flavour, texture, and functionality. By using fermented food communities as model systems, we address fundamental questions in ecology and evolution while developing novel starter cultures, fermentation processes, and food innovations that support the green transition and more sustainable, healthy, and resilient food systems.

In this specific project we aim to develop a local caffeine-free coffee alternative by applying knowledge form traditional coffee fermentation on a local waste stream currently used dried as coffee alternative but lacking flavour complexity of fruity and sour notes that can only be added through fermentation.  The project will screen different substrate combinations to match the organoleptic properties of coffee, develop a new caffeine-free prototype guided through genome-scale metabolic models developed at Cambridge University with Prof. Kiran Patil. The resulting prototype will be studied to further refine the model but also to assess its microbial composition, assess food safety, its flavour profile via metabolomics and sensory analysis and scalability potential. 

Responsibilities and qualifications
As a PhD candidate, you will take a leading role in driving the scientific progress of the project. You will be responsible for planning, designing, and executing experiments, coordinating activities with collaborators within the group as well as external partners, and ensuring the timely progression of the research.

Your responsibilities will include:

• Deep scientific understanding of the field and all relevant literature
• Playful experimentation with culinary product development
• Designing and execution of experiments on characterizing the ferments metagenomics, metabolomics, sensory analysis
• Bioinformatic analysis, data integration and statistical analysis
• Visualizing results and communicating findings to diverse scientific audiences
• Publishing research findings in international journals
• Presenting your work at international conferences and scientific meetings
• Collaborating closely with researchers across disciplines and contributing to an open, collaborative research culture

We are looking for a highly motivated and ambitious candidate who thrives in a dynamic research environment and is excited by the opportunity to work transdisciplinary at the intersection of ethnography, gastronomic craft and microbiology.

The ideal candidate has:

• Experience in microbiology
• Experience in microbial food innovation
• Some experience in food fermentation and product development
• Some experience in generating and analysing metagenomic and metabolomic data
• A strong interest in sustainable food systems, food fermentation and microbial ecology

In addition, you:

• Demonstrate a high level of motivation, curiosity, and scientific integrity
• Are able to work independently and take ownership of your research
• Take a proactive approach to identifying opportunities and solving problems
• Learn quickly and adapt effectively to new methods and challenges
• Have strong communication skills, including scientific writing and oral presentations in English
• Enjoy working in collaborative and interdisciplinary teams
• Be comfortable in an interdisciplinary environment, where different types of knowledge co-exist
• Are open to and interested in different cultures
• Are organized, structured, and committed to maintaining high-quality documentation and reproducible research practices
• Be patient, charitable, curious and playful – key qualities for interdisciplinary work 

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. 

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and appointment terms 
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 3 years. 

The preferred start date is 01.01.2027.
