Field of Expertise:
Mathematical Modelling

At BIOMATH, we develop and apply mathematical models and methodologies for the analysis and optimization of (bio)processes. The primary focus is on mechanistic models used to support a variety of priority sectors such as pharmaceutical manufacturing technology.

During the last decade, the focus of the group shifted towards a triangle of modelling frameworks, subsequently extending the conventional bio-kinetic models with Computational Fluid Dynamics (CFD) and Population Balance Models (PBM).

  • CFD extends the level of spatial description of reactor systems and was felt as a need since systemic models, such as tanks-in-series approach, became limiting.
  • PBM was a logical addition since this was the topic of Prof. Nopens’ PhD dissertation. This framework allows to model the dynamics of distributed properties of a population of individuals.

Also, combinations of the frameworks can be used to answer complex problems. In that sense, one of the current strategies of BIOMATH is the development and experimental validation of complex models for process understanding. Such a detailed modeling step can be followed by a model reduction step to create simplified models. In the sense that they are mathematically and computationally easier to solve, more accurate, require less calibration and, therefore, have a higher predictive power as compared to lumped process models. BIOMATH has consequently gained extensive expertise in the fields of computational fluid dynamics, population balance modelling and bio-kinetics.

Field of Expertise:
Chemical Technology

The Laboratory for Chemical Technology (LCT) integrates chemical science and engineering in its research on catalysis, polymerization, kinetics, reactor design and process design. LCT is part of the Department of Materials, Textiles and Chemical Engineering within the Faculty of Engineering and Architecture at Ghent University in Belgium. LCT aims at research excellence and bottom-up innovation in the framework of technological, industrial, and societal challenges.

The research within LCT is based around six themes:

  • Polymer design: This research theme specifically aims at the design of new polymeric materials up to industrial scale, considering advanced multi-scale computational tools. Our goal is to take control over the entire microstructure of individual polymer chains, taking into account economic and environmental constraints.
  • Catalyst design: This research theme aims at the full exploitation of existing reactor technologies and the development of new reactor technologies. Main focus is on the study of the delicate interplay between reaction kinetics and mass, energy and momentum exchange phenomena.
  • Reactor engineering: This research theme aims at the full exploitation of existing reactor technologies and the development of new reactor technologies. Main focus is on the study of the delicate interplay between reaction kinetics and mass, energy and momentum exchange phenomena. Given the large scale of most commercial chemical processes, the smallest improvement in reactor design has a huge impact on the use of resources and the operating costs.
  • Circular process design: Today we must consider the whole lifecycle of our resources. Fundamental changes are needed in all these parts of the process industry, in particular in the design of these processes where exergy analysis, resource efficiency and life cycle analysis are fed by fundamental process simulation data that account accurately for the important chemical and physical phenomena on different scales. 
  • Low carbon technology: The transition from a raw material base towards an almost carbon neutral economy is one of the biggest challenges. Catalysis is a key enabling factor to allow the development of new sustainable processes and technologies and thus plays a critical role to realize transition from a linear to a circular economy. Consequently, the development of catalysts and related catalytic technologies for the use of CO2 to produce chemicals and fuels, and renewable energy in chemical production is becoming a key area.
  • Renewable chemicals and technology: In this research theme, emphasis is on the development of fundamental so-called microkinetic models together with dedicated ab initio calculations and elaborate catalyst characterization to enable this extension. The individual phenomena investigated range from the chemical kinetics, over mass and heat transport phenomena and phase/thermodynamic effects, to non-ideal reactor hydrodynamics.

Field of Expertise:
Nanomedicines, biopharmacy

Currently the Laboratory of General Biochemistry & Physical Pharmacy houses 4 closely collaborating research groups: the Biophotonic Research Group, the Ocular Delivery Group, the Lung Delivery Group and the Vaccine Delivery Group. The global research focus of our teams is on the delivery of bio-therapeutics, especially nucleic acids. Our teams offer a multifaceted portfolio of competencies including pharmacology, material knowledge and expertise in drug delivery, nanotechnology, cell biology, immunology, biophysics, optics and bio-photonics.

Pharmaceutical Engineering

Field of Expertise:
Pharmaceutical Engineering

Given the complexity and increasing diversity of products and technologies in (bio-)pharmaceuticals processing, it is clear that there will be no “one size fits all” solution for new process development and manufacturing requirements. The research in Pharmaceutical Engineering (PharmaEng) group involves development and application of a digital twin of equipment, processes, and the environment, where functions and properties are treated using various mechanistic frameworks. The research group aims to apply these digital twins to deliver solutions covering all the three aspects of pharmaceutical process development – product design, process design, and process improvement. Modeling frameworks based on first-principles such as DEM, FEM, CFD, and PBM in combination with kinetic, thermodynamic models will be used to design and optimize the system to deliver drug substances and products with desired physical properties.

Our research areas include both classical batch and continuous processing unit operations. Within these fields, we have an extensive expertise in following domains:

  • Process equipment design and optimization
  • Process and equipment scale-up
  • Detailed modeling of pharmaceutical processes for mechanistic insights
  • Advanced pharmaceutical manufacturing control strategy

Field of Expertise:
Process Analytical Technology

The Laboratory of Pharmaceutical Process Analytical Technology (LPPAT) focuses on the implementation of PAT systems in innovative pharmaceutical production processes and therefore has always worked in close collaboration with the Laboratory of Pharmaceutical Technology of Prof. Dr. C. Vervaet and is part of the QbD and PAT Sciences Network. 

Manufacturing processes of interest:

  • Freeze-drying
  • Continuous wet granulation
  • Production of solid oral dosage forms
  • Continuous melt granulation

Implementation of PAT systems:

  • The development and implementation of process analyzers in the process stream allowing real-time collection of critical process and (intermediate) product information.
  • Data-analysis methods (chemometrics) allowing to extract useful information from the large datasets that process analyzers supply. Process analyzers are only valuable if they provide the desired information with sufficient accuracy. Being able to build accurate and robust models to reliably translate the data (e.g., obtained spectra) into process or product knowledge is crucial.
  • Design of Experiments (DoE) to maximize the information content from experimental series while keeping the number of experiments low. As the process (step) endpoints and the intermediate or end product properties (e.g., product solid state, chemical properties, physical properties,…) are influenced by numerous process and formulation variables, appropriate experimental design approaches must be applied to find out which variables and variable interactions significantly influence processes and product properties.
  • Statistical process control and visualization: a final aim of implementing PAT systems in pharmaceutical production processes is complete process control. Based on process knowledge and process models, the information obtained in real-time should be used for guiding the process to its desired state, possibly allowing real-time release. Early warnings should be given when a process is moving into an unwanted direction and the process models should allow to determine how process settings must be adapted by operators to lead the process to its desired state, thereby reducing batch rejection.
  • Mechanistic modelling: empirical modelling is based on historical data and as such they are of limited use in new applications outside the experimental space studied. Apart from cause-and-effect between variables, not much else is required in terms of process knowledge. Mechanistic modelling is based on the fundamental understanding of the underlying physics and chemistry governing the behaviour of the process. Hence, mechanistic modelling does not require much data for model development, and hence is not subject to the idiosyncrasies in data. Mechanistic modelling forces to fundamentally and completely understand processes. The different steps of mechanistic modelling are mentioned in appendix. This new approach of modelling of pharmaceutical processes should allow making useful process simulations and process predictions.

Laboratory of Pharmaceutical Technology

Field of Expertise:
Pharmaceutical technology

The research at the Laboratory of Pharmaceutical Technology (Ghent University) focuses on the development of innovative drug dosage forms (mainly solid dosage forms) for human application as well as for veterinary use. These dosage forms are based on pharmaceutical accepted excipients used as such or as mixtures to impart specific drug release properties (immediate, controlled or sustained release) to the formulation. The lab has a strong research focus on continuous manufacturing techniques.

The projects at the Laboratory of Pharmaceutical Technology are focused on the following topics:

  • Granulation: Current research mainly focusses on process and formulation development for twin screw wet and melt granulation as well as their downstream processes. Therefore, evaluating the interplay between raw material properties and process settings is of high interest. This approach is used to (i) derive preferred excipients platforms for novel APIs, (ii), evaluate the impact of batch-to-batch variability and (iii) evaluate the applicability of botch conventional and non-conventional excipients for continuous processing.
  • Tabletting: Ongoing work investigates the influence of raw material and blend properties on the die-filling and tabletability during continuous manufacturing. Residence time distributions in the feedframe and influence of different process parameters are being studied. In addition, the influence of feeding and blending during continuous direct compression on the tablet content uniformity is evaluated.
  • Compaction simulation: Currently, our team is working on the evaluation of the external lubrication system on the compaction simulator (Styl’One Evolution). In addition, the correlation between the tableting process and tablet quality of tablets produced on the Styl’One Evolution tableting instrument and Modul™ P rotary tablet press is studied.
  • Hot-melt extrusion and 3D-printing: Hot melt extrusion is used for designing sustained release dosage forms using conventional and non-conventional polymeric materials for controlled drug release. On the other hand, the extrusion process is used to enhance the bioavailability of poorly soluble drugs by preparing molecular dispersions for immediate release dosage forms. The development of personalized 3D dosage forms with versatile release profiles is also one of our research interests. Recently, FDM 3D printing was used as an alternative HME downstream processing technique to produce personalised medicines for the manufacturing of high drug loaded dosage forms, hence offering a lot of formulation freedom for the on-demand production of personalized dosage forms at the point-of-care.
  • Spray-drying: Research on the spray dryers is focussed on formulation of particles for dry powder inhalation, co-processing to obtain particles with the desired properties (e.g. improved compressibility, flowability) and creation of micro-particles for oral antigen delivery.
  • Freeze-drying: Our lab developed a continuous freeze-drying process in collaboration with the Laboratory of Pharmaceutical Process Analytical Technology. This continuous freeze-drying concept is based on spinning the vials during freezing (I.e. spin-freezing) and on non-contact energy transfer via infrared radiation during drying. This improves process efficiency and product uniformity compared to conventional batch drying. Our research focus is development of a formulation strategy and optimisation of the models used in the different steps of continuous freeze-drying.

(Bio) Organic Chemistry

The Synthesis, Bioresources and Bioorganic Chemistry (SynBioC) Research Group is active in the broad field of organic synthesis with projects ranging from the synthesis of new bioactive compounds for applications in the medicinal and the agrochemical field, the isolation and study of natural products, the use and chemical modification of renewable resources, to the implementation of green chemistry, microreactor technology and photo chemistry.

Within the framework of organic and bioorganic chemistry, the following research lines are elaborated:

  • The chemistry of small-ring azaheterocycles: This research involves the study of regio- and stereoselective ring transformations of constrained (phosphonylated) azaheterocycles such as aziridines, azetidines and beta-lactams. Next to the fundamental aspect of designing and evaluating new synthetic methods, the application of these techniques is also employed for the construction of a broad variety of heterocyclic target compounds with biological interest (diversity-oriented approach).

  • Green chemistry and renewable resources: Renewable chemicals and materials are currently a hot topic in research and industry. The depletion of fossil resources and the exhaust of greenhouse gases force us to think about alternative sources for the chemical industry and the energy sector..Our research group focuses on the modification of non-fossil resources towards renewable chemicals, such as the modicification of biopolymers (inulin, chitosan), the use of 10-undecenoic acid (derived from castor oil) and the production of biofuels and renewable fuel additives.
  • Microreactor technology: Microreactor technology (MRT) provides a number of specific advantages compared to batch processes: it is often more selective and efficient, has a better mass and heat transfer capacity, consumes often less reagents and solvents, has good safety features and allows to work with very reactive and/or toxic reagents. The SynBioC research group is active in the application of microreactor technology for multicomponent reactions, reactions using dangerous reagents, fotochemical and low temperature reactions.
