Do you want to contribute to making dairy food processing more sustainable and do research on future piezoelectric membrane reactor technologies? At DTU Energy this is what we do, among other things, and we are looking for a new team member.

Large amount of milk is produced on a global scale, approximately 850 million tons in 2018, and dairy market size is estimated at $442 billion. Due to its perishable nature, it is important that milk is processed to extend shelf life and reduce waste, and here, lactic acid bacteria (LAB) plays an essential role. Approximately half of the milk produced, 400 million tons, is fermented using LAB, typically producing cheese, yoghurt and fermented butter. One of the greater challenges in dairy operation is phages, which are bacterial viruses. To counter this, the current practices involve maintenance of a sterile environment and use of quite expensive starter LAB culture. Even then, ca. 10% of all the milk fermentation is negatively impacted by phages. Thus, solutions that can prevent the phages reaching LAB while maintaining high LAB activity will play a key role in  making dairy food processing more sustainable by reducing waste.

We have recently won support for an innovative research project that focuses on conceptual development of piezoelectric membrane reactors to grow the robust lactic acid bacteria for dairy applications, from the VILLUM FONDEN.  The project targets development of reactors using ceramic processing methods (e.g., extrusion, coating etc). This involves the development of slurry/paste/ink formulations and optimization of shaping and consolidation parameters to realize the desired reactor architecture. Adjusting the microstructure to achieve the required electrical properties will complement the development of the reactor. Validation of the concept involves testing of the reactor using lactic acid bacteria.

For this project, we need a postdoc to strengthen our capabilities in the processing and shaping of piezoelectric and zeolite-type materials that includes formulation of stable slurries and inks and components fabrication along with their physical, structural, chemical, electrical and biological characterisation. You will be working in a team of researchers from DTU that will include lab technicians and experienced researchers.

The main activity will take place at the Department of Energy Conversion and Storage at DTU Lyngby campus and you will be a part of the research section; “Solid State Chemistry”.

Qualifications
For applicants to be qualified they should have:

  • A PhD degree in engineering, physics, chemistry or similar
  • The ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamic group
  • Good communication skills in English, both written and spoken
  • Experience in several of the following areas is further advantageous; materials development and processing, physical, chemical, structural, electrical and biological characterization

Experience with piezoelectric ceramics and zeolite materials processing and characterization is highly desirable as is familiarity with microbiology. Research experience besides your PhD-work is further an advantage.
