and Biomolecular Engineering

I am a physical chemist with focus on fundamental and applied experimental research. On my homepage you can find details about my scientific work (research tab) and teaching (video tab).

The following graph gives an overview about my research. Combining liquid-liquid phase separation with various surface active materials (lipids or diblockcopolymers, ionic or nonionic surfactants, surface active particles) results in different phenomena that have allowed me to fabricate a variety of novel and functional soft materials.

Overview of my research: Complex emulsion formation by liquid-liquid phase separation


Recent research: Bijels


A specific example of my research is the interfacial self-assembly of microscopic solid particles. Coupled with liquid-liquid phase separation this leads to the formation of new types of bicontinuous interfacially jammed emulsions (bijels).

Bijels consist of two interwoven pore networks, each filled with a liquid that is immiscible with the other. The interface between these liquids is stabilized by microscopic particles. This architecture provides Bijels with high interfacial areas and robust mechanical properties.

My work facilitates the simple fabrication of bijels with many different building blocks, controllable architectures and morphologies.

Bijels have great potentials for applications in food-technology, as filtration membranes, for microfluidics and as catalytic reaction media.

In the future I plan to investigate the complex mechanisms behind bijel formation and also demonstrate high-impact applications of bijels.
