3 years financial support to pursue a PhD (including Living, Mobility and Family Allowance according to H2020-MSCA-ITN regulations)
ESR14 to be recruited by KU Leuven/BioTeC+ will set-up and execute fermentations with cheeses (plant-based or hybrid) and study the effect of various storage/ripening conditions on flavour development and microbial stability. Based on the data obtained, ESR14 will develop a mathematical model to predict condition-dependent characteristics of plant-based cheeses. Correlations between ripening conditions, cheese properties and the final flavour of the product will be investigated using linear and non-linear methods. Based on the identified relations and the data available, a regression model based on machine learning methods will be trained and validated for the prediction of the properties of cheese analogues.
This project is expected to generate a mathematical in silico model that predicts the impact of ripening conditions of semi hard cheese on flavour formation which will be extended to plant based cheese analogues based on high throughput experimental data (through in vitro cheese models) obtained in the project. The development of plant-based cheese analogues (in vitro cheese models) will set new standards for generating reproducible data sets.
In total, 2 months will be spent analysing data ripening conditions and 6 months performing experimental work flavour development at NIZO Food Research BV (NIZO) in Netherlands and 2 months performing flavour analysis at the French National Research Institute for Agriculture, Food, and the Environment (INRAE) in France.

Host Institution Description
The vision of BioTeC+ (Chemical & Biochemical Process Technology & Control) is to consolidate and strengthen both its international research position and its societal impact by focusing on a carefully selected number of research areas and application domains in applied chemistry/chemical and biological process engineering.
At present, these application domains can be characterized by the keywords industrial biotechnology, closing the waste/water cycle, and public health. These constitute the pillars (columns) (bio)chemical reactions & reactors, (biological) waste(-water) treatment systems, and predictive microbiology/microbial risk assessment within BioTeC’s research matrix. This broad range of application domains is supported by our long standing systemic (systems and control) approach towards applied chemistry/chemical and biological process engineering. The research areas system theory and analysis, process model identification (including optimal experimental design), process monitoring, optimization and model based control characterize the transversal rows in the research matrix. These rows constitute the longstanding fundament of BioTeC’s research covering and underpinning all application domains (pillars).
The underlying motivation is that model based solutions to chemical and biological process design, optimization and control are superior in performance and robustness as compared to plain heuristic approaches. In the case of microbial conversions for example, process optimization is aimed at by creating optimal environmental conditions for the cell. Therefore, this line of research is fully complementary to process optimization by genetically modifying the cell itself. To realize this mission, interdisciplinary research is required: both concepts and techniques from mathematical modeling and systems and control as well as detailed (micro-)biological/(bio-)chemical knowledge are essential building blocks for high performance process identification, intensification and control algorithms.
KU Leuven/BioTeC+ runs a state-of-the-art L2 accredited laboratory for experimental predictive microbiology research, as well as high-end computing facilities. Our 6 postdocs and 14 PhD researchers are involved in numerous international research projects and networks, including 5 ongoing EU projects. As a most international and inclusive team, we look forward to welcome you on our campus in the vibrant city of Gent, Belgium!
A substantial part of the work will be performed in the laboratories of NIZO in Ede, The Netherlands. NIZO (www.nizo.com) is a leading company in contract research for better food and health. NIZO has one of the most advanced R&D centers in the world and brings the latest food technologies to life in their food grade processing center. Main focus is on the development and applications of innovations for the global food industry and related markets. Customers value their gains in product quality, sustainability, cost effectiveness and speed to market. NIZO is continuously looking for new ways of improving food products, and at the same time quality of life. Substantial knowledge and expertise in bacteria, proteins and processing is the starting point of numerous contribution to innovation.
