PhD Position Uncertainty Quantification of Physics-Based and Machine Learning Models of Critical Industrial Components

Updated: about 2 months ago
Deadline: 11 Feb 2024

The manufacturing sector is and will continue to experience an evolving trend, marked by the exponential growth of additive manufacturing, the ongoing 4th industrial revolution (Industry 4.0), and an increasing demand for the customization of manufactured products. However, the production and economic growth of the manufacturing sector need to meet unpostponable sustainability guidelines and criteria. This means minimizing energy losses as much as possible. To fully sustain this ongoing transition of the EU manufacturing sector, two key technical challenges need to be simultaneously tackled: the uncertainty induced by the production process (e.g., human errors, geometrical and material variabilities caused by the manufacturing process and/or by the machine setup) and the increasing complexity of the manufactured goods characterized by the critical parts or components.

In order to tackle these challenges, the Active PRoduct-to-Process LearnIng fOR Improving Critical Components Performance (APRIORI) training network has been created. This project (no. 101073551) is funded under the Marie-Sklodowska-Curie Actions Doctoral Networks within the Horizon Europe Programme of the European Commission.

The ambition of APRIORI is to develop 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 the manufacturing sector in Europe. APRIORI’s mission is to train the next generation of doctoral candidates to fully sustain the ongoing transition of the EU manufacturing sector. More precisely, APRIORI offers 15 doctoral positions within a multidisciplinary and international network, involving universities (KU Leuven, TU Delft, Aalborg University), a research institute (Jozef Stefan Institute), and small- and large-scale industry (Grundfos Holding AS, Materialise NV, Temporary Works Design 9 B.V., Qlector) from manufacturing, equipment design, manufacturing software, and data-driven solutions sectors with the relevant expertise to create the coordinated research environment needed to develop integrated design strategies to produce better, long-lasting, and sustainable products. In addition to their research activities, the doctoral candidates will participate in peer-educational initiatives, further enhancing the collaborative and scholarly dimensions of the program.

For this position, you will work on the development of efficient techniques for assessing uncertainties in the input parameters of physics-based models on the design performance of critical industrial components. You will investigate the combination different approaches for uncertainty quantification considering both physics-based models (Finite Element Models in particular, and its stochastic counterparts such as StatFEM) and machine learning-based surrogates (e.g. Multifidelity Gaussian Processes, Polynomial Chaos, Conformal Prediction). The key challenge will be to obtain efficient uncertainty metrics while avoiding large numbers of simulations of expensive-to-run high-fidelity models.

Close collaboration with other PhD projects within APRIORI is also envisioned, with special focus on comparing, combining and exploiting advanced probabilistic models developed by the other candidates (e.g. Bayesian networks, vine-copulas and novel Monte Carlo samplers). The project is embedded in a cross-departmental collaboration within the faculty of Civil Engineering and Geosciences, including the Department of Mechanics, Materials, Management and Design (3MD), the Department of Hydraulic Engineering (HE) and the Department of Engineering Structures (ES). You will be working on an exciting topic with a strong interdisciplinary nature.

We are in search of a highly motivated professional who enjoys working in a multidisciplinary setting.

If the following characteristics resonate with you, consider joining us on this PhD journey:

  • You already have a good background in numerical methods for scientific computing, with focus on computational mechanics tools such as the Finite Element Method, on probability and statistics and preferably also on scientific machine learning.
  • You have earned an MSc degree in fields like industrial engineering, applied mathematics, applied physics, mechanical engineering, civil engineering or similar.
  • Effective communication and teamwork within multidisciplinary groups come naturally to you.
  • You have experience in programming languages such as Python and C++, and are eager to hone these skills further.

This is a unique opportunity to advance both your academic and practical skills and to create a strong international network, and we encourage you to apply if you meet these criteria.
