Research Interests

Please check our Polymers & Microfluidics Group website

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, X-ray and neutron scattering.

We are interested in exploring microfluidics for soft matter processing, seizing their commensurate length and timescales. We are also interested in the patterning and device fabrication and explore ‘Frontal photopolymerisation’ (FPP) to rapidly create 3D structures that, moreover, are compatible with an array of organic solvents. We also developed a sound theoretical understanding of the nature of front propagation, which exhibits intriguing kinetics. In terms of applications, we work on microprocessing as a means to tune structure and performance of complex fluids, as well as interfacial tensiometry, and coupling of charcterisation approaches such as scattering. 

Finally, we develop high-throughput and combinatorial approaches for polymer mixtures and network formation. We are now elaborating on scattering and spectroscopic tools to elucidate aspects of morphology and stability of elusive soft matter systems.
