Microfluidic Biophysics and Multiscale Bioengineering

My research bridges microfluidics, membrane biophysics, molecular dynamics, computational modelling, and biomedical engineering. It focuses on developing experimental platforms and computational methods for studying biological membranes, their physical properties, and their interactions with molecules and cells.

A central element of my current work is the development of microfluidic platforms for biophysical experiments. These systems are designed to provide precise control over flow, mass transport, diffusion, and the local experimental environment, enabling quantitative studies of lipid membranes and living cells.

My research combines microfluidic engineering, microscopy, molecular dynamics simulations, computational fluid dynamics, and quantitative data analysis into an integrated experimental and computational workflow.

02

Microfluidic Platforms for Membrane Biophysics

A major focus of my work is the development of microfluidic biophysical chips for the generation, manipulation, and characterisation of lipid membranes.

These platforms are used to generate and study giant unilamellar vesicles (GUVs), which provide well-controlled model systems for investigating membrane structure, mechanics, morphology, permeability, and interactions with membrane-active molecules.

Microfluidics offers precise control over the physical and chemical environment in which vesicles are generated and analysed. This allows us to study membrane behaviour under defined flow and transport conditions while combining microfluidic operation with fluorescence and confocal microscopy.

The resulting platforms provide a controlled experimental environment for studying membrane properties and for testing hypotheses derived from molecular and theoretical models.

03

Molecular Dynamics and Membrane Biophysics

The experimental microfluidic work is complemented by molecular dynamics (MD) simulations, primarily using NAMD. MD simulations are used to investigate membrane structure and dynamics at the molecular scale, including interactions between lipid bilayers and membrane-active molecules or peptides. This provides a computational framework for interpreting experimental observations and for studying mechanisms that are difficult to access directly through experiments.

An important aspect of my research is therefore the connection between molecular-scale simulations and experimentally accessible membrane properties.

This multiscale approach makes it possible to connect molecular mechanisms with observations obtained from model membrane systems and, subsequently, biological experiments.

04

Experimental Studies of Membranes Systems

The microfluidic and membrane platforms are used to investigate dynamic membrane processes, including interactions of molecules with lipid bilayers, membrane deformation, permeability-related phenomena, and morphological changes.

Working with controlled model membrane systems allows individual physical mechanisms to be investigated in a simplified and reproducible environment before moving towards more complex biological systems.

This creates a progression from defined lipid membranes and GUVs to cellular systems, while maintaining quantitative control over the experimental environment.

05

Cell Culture Under Flow

An important development of the microfluidic platform has been its extension from model membranes to living cell cultures under flow.

We have successfully established cell culture in continuous flow within our microfluidic chips, demonstrating that the devices can support experiments involving living cells under controlled hydrodynamic conditions.

This creates an important bridge between membrane biophysics and cellular-level experiments. Instead of studying cells only under static culture conditions, the microfluidic environment allows us to investigate cellular behaviour under defined flow and transport conditions.

06

Computational Fluid Dynamics

The development of microfluidic devices is supported by computational fluid dynamics (CFD).

I use OpenFOAM to model flow and transport phenomena inside microfluidic systems, including velocity fields, mixing, diffusion, mass transport, and residence-time behaviour. CFD is used as part of the device-development process rather than as a separate computational activity. Numerical simulations help evaluate and optimise microfluidic geometries, understand experimental conditions, and interpret biological and biophysical observations.

The combination of simulation and experiment is particularly important for developing reproducible microfluidic systems in which local flow and transport conditions directly affect the biological experiment.

07

Quantitative Data Analysis

Experimental and computational results are analysed using custom scripts developed in Python and MATLAB. These tools are used for quantitative image analysis, statistical analysis, extraction of biophysical parameters, data processing, and integration of experimental results with computational models. The aim is to move from qualitative microscopy observations towards quantitative and reproducible measurements that can be compared with simulations and used for model validation.

08

Multiscale Research Framework

My research connects several complementary levels of biological and physical description:

Molecular scale - Molecular dynamics simulations of lipid membranes and membrane-active molecules.
Microfluidic scale - Engineering of controlled environments for membrane and cellular experiments.
Device scale - CFD modelling of flow, mixing, diffusion, and mass transport.
Biophysical scale - Experimental characterisation of GUVs and lipid membrane behaviour.
Cellular scale - Cell culture and biological experiments under controlled flow.
Data scale - Quantitative analysis and integration of experimental and computational data.

This framework allows physical mechanisms to be studied across scales rather than as isolated phenomena, connecting molecular interactions with membrane behaviour and ultimately with cellular responses.

09

Research Through BSc Projects

The research environment also supports interdisciplinary engineering projects combining microfluidics, membrane biophysics, molecular simulation, biomedical engineering, and computational methods.

Examples of diploma projects I have supervised include:

Microfluidic Formulation of Lipid Nanocarriers

Microfluidic formulation of nanolipid carriers using micromixers and Dean vortices for active compound encapsulation

An engineering project focused on microfluidic mixing and secondary Dean-flow effects for the formulation of lipid-based nanocarriers and encapsulation of active substances.

Molecular Dynamics of Membrane-Active Peptides

A computational project investigating interactions between membrane-active peptides and lipid bilayers using molecular dynamics simulations.

Liposomal Encapsulation and Coating

An experimental project focused on lipid-based encapsulation and quantitative evaluation of a liposomal delivery system.

Pharmacokinetic Modelling

Clinical Decision Support Application for Vancomycin Therapeutic Drug Monitoring Using Pharmacokinetic Modeling

A project combining pharmacokinetic modelling, biomedical data analysis, and software engineering to support therapeutic drug monitoring.

10

Additional Application: Nanolipid Particles through Microfluidics

As an additional application of the microfluidic technology, I also work on the microfluidic formulation of nanolipid particles (NLPs) and lipid-based delivery systems.

This direction involves the use of controlled microfluidic mixing and transport to investigate the formulation and encapsulation of active compounds in lipid-based nanocarriers.

While this is a more application-oriented branch of my work, it builds directly on the same expertise in microfluidic design, flow control, transport phenomena, lipid systems, and quantitative characterisation developed through the core membrane-biophysics research.

11

Research and Technology Development

The overarching goal of my work is to develop integrated experimental and computational platforms for quantitative biophysics.

Rather than treating microfluidics, molecular simulations, and biological experiments as separate activities, I combine them into a common research framework in which computational models inform experimental design and experimental observations are used to validate and refine those models. This approach provides a technological basis for research in membrane biophysics, biomimetic systems, cellular transport, microphysiological experimentation, and biomedical microdevices.

My work therefore combines microfluidic engineering, molecular dynamics, CFD, membrane biophysics, live-cell experiments, and quantitative data analysis to develop reproducible experimental systems for investigating biological processes across multiple scales.
