The KU Leuven Mecha(tro)nic System Dynamics division (LMSD) and the Campus Diepenbeek Polymer Processing & Engineering (PPE) groups are searching for a research engineer to join its team to work in the challenging Horizon Europe MSCA project APRIORI: Active PRoduct-to-Process LearnIng fOR Improving Critical Components Performance.

  • This PhD is part of the Horizon Europe MSCA doctoral network APRIORI (Active PRoduct-to-Process LearnIng fOR Improving Critical Components Performance). APRIORI is an international consortium of high-profile universities, research institutions and companies located in Belgium, the Netherlands, Denmark and Slovenia. The European manufacturing sector is experiencing and will continue experience a transition, characterized by the exponential growth of additive manufacturing, the 4th industrial revolution (Industry 4.0) and an increasing demand of customization of the manufactured products. The ambition of the APRIORI training network is to fully support this evolution by training 10 doctoral candidates (DCs) and future innovators to deal with two key technical challenges within the manufacturing sector: the uncertainty induced by the production process and the increasing complexity of the manufactured goods characterized by the critical parts or components. This will be achieved by developing the skills and new technologies that will enable for the first time the development of a unique integrated product design strategy that will drastically improve the performance of critical parts or components under uncertainties.

  • As DC4 in the APRIORI training network you will develop strategies to quantify the effects of local variations in e.g. density or geometry, compared to the nominal design, on the stopband behavior of 3D printed locally resonant metamaterials. By quantifying the uncertainties on geometry, density and stiffness distributions and by assessing the spread on the designed stopband location and width for different (vibro-)acoustic metamaterial designs, you will derive design rules linking nominal dimensions via the production process to a quantified spread on the expected result, accounting for uncertainties. These will allow ensuring a minimal performance for metamaterial designs, taking into account the effects of manufacturing uncertainties, and provide a leap forward towards the widespread use of locally resonant metamaterials as NVH solutions for industrial applications.

  • The research is hosted by the Mecha(tro)nic System Dynamics division (LMSD), which currently counts >100 researchers and is part of the department of mechanical engineering of KU Leuven. The research group has a long track record of combining excellent fundamental academic research with industrially relevant applications, leading to dissemination in both highly ranked academic journals as well as on industrial fora.

  • Profile

    If you recognize yourself in the story below, then you have the profile that fits the project and the research group.

  • I have a master degree in engineering, physics or mathematics, obtained no longer than four years ago, and performed above average in comparison to my peers.
  • I am proficient in written and spoken English.
  • I haven't had residence or main activities in Belgium for more than 12 months in the last 3 years.
  • During my courses or prior professional activities, I have gathered some basic experience with the physical principles of (vibro-)acoustics and the related measurement and numerical modelling techniques, and/or I have a profound interest in these topics.
  • As a PhD researcher of the KU Leuven Noise and Vibration Research Group I perform research in a structured and scientifically sound manner. I read technical papers, understand the nuances between different theories and implement and improve methodologies myself.
  • Based on interactions and discussions with my supervisors and the colleagues in my team, I set up and update a plan of approach for the upcoming 1 to 3 months to work towards my research goals. I work with a sufficient degree of independence to follow my plan and achieve the goals. I indicate timely when deviations of the plan are required, if goals cannot be met or if I want to discuss intermediate results or issues.
  • In frequent reporting, varying between weekly to monthly, I show the results that I have obtained and I give a well-founded interpretation of those results. I iterate on my work and my approach based on the feedback of my supervisors which steer the direction of my research.
  • I feel comfortable to work as a team member and I am eager to share my results to inspire and being inspired by my colleagues.
  • I value being part of a large research group which is well connected to the machine and transportation industry and I am eager to learn how academic research can be linked to industrial innovation roadmaps.
  • During my PhD I want to grow towards following up the project that I am involved in and representing the research group on project meetings or conferences. I see these events as an occasion to disseminate my work to an audience of international experts and research colleagues, and to learn about the larger context of my research and the research project.
  • Offer
  • A remuneration package competitive with industry standards in Belgium, a country with a high quality of life and excellent health care system. You will receive a monthly gross salary of 3400€. The net income will be lower since a deduction of income tax, the social contributions, and other permitted deductions need to be considered. In addition to the net salary you will receive a mobility allowance of 600€.
  • An opportunity to pursue a PhD in Mechanical Engineering, typically a 4 year trajectory, in a stimulating and ambitious research environment.
  • Ample occasions to develop yourself in a scientific and/or an industrial direction. Besides opportunities offered by the research group, further doctoral training for PhD candidates is provided in the framework of the KU Leuven Arenberg Doctoral School (https: //, known for its strong focus on both future scientists and scientifically trained professionals who will valorise their doctoral expertise and competences in a non-academic context. More information on the training opportunities can be found on the following link: https: //
  • A stay in a vibrant environment in the hearth of Europe. The university has campuses across Flanders, your research will be mainly located at Campus Diepenbeek (https: // www. campus/about/index.html) 10 minutes located from the city Hasselt, 50 min from Leuven and 1h from Brussels. Further information can be found on the website of the university: https: // www. leuven/
