The Hybrid Assembly Group (HAG) of Dr. Leonie van ‘t Hag focuses on the sustainable production and processing of soft materials. We do this by investigating the structure – property relationships for food, biological and biomedical applications. The group uses a combination of chemical engineering, physical chemistry, biochemistry and cell biology approaches. We have a focus on using advanced (light, X-ray and neutron) scattering and microscopy techniques to investigate the micro- and nano-structure of the materials depending on processing parameters. We are particularly interested in hybrid protein–lipid materials. This includes lipid self-assembly materials for the encapsulation of integral membrane proteins, therapeutic peptides and bioactive components, as well as protein–rich food products such as vegetables, nuts, dairy and pulses.
