My research interests are in soft condensed matter, in particular in complex polymer mixtures, multicomponent systems, often containing particles and copolymers. We study the thermodynamics and dynamics or polymer blends with a combination of real- and reciprocal-space techniques, including microscopy and AFM, and light and neutron scattering.

We employ microfluidics for automation (e.g. high throughput screening and optimisation) and to exert well-defined external fields, including thermal and flow fields of prescribed magnitude and type. In this process, I became interested in microfabrication and investigate ‘Frontal photopolymerisation’ (FPP) to rapidly create 3D structures with light. FPP is a rich directed solidication process with fascinating mechanisms, kinetics and instabilities. We also developed a sound theoretical and experimental understanding of the nature of front propagation, and have applied it to microfluidic fabrication. In recent years, we have placed considerable effort in coupling microfluidics with scattering of neutrons and X-rays (SANS and SAXS) which enables us to probe the molecular and mesoscopic consequences of external fields on complex fluids with unprecedented precision.  We are now elaborating on scattering and spectroscopic tools to elucidate aspects of (meta-)stability of elusive soft matter systems.
