Emulsion Gel

PhD Project

I am an experimental chemical physicist working on protein-stabilised emulsions and gels for food applications (particularly ice-cream). I study the formation of networks in mixtures of proteins in solutions and protein-stabilised droplets by relating their mechanical properties with their microstructures. It is also interesting to compare these systems with similar ones using more model colloidal particles to stabilise droplets (Pickering emulsions) and to form gels. Rheometry, rheo-imaging, confocal microscopy, image analysis are the main techniques used for this study.
My PhD project is supervised by William Frith (Unilever) and Paul Clegg (University of Edinburgh).


In preparation! Please get in touch if you want to know more about my work.

Other activities

I am very keen on science communication, and I enjoy any opportunity to share my passion of soft material science, even more if that involves making people play with squishy materials. I am also happy to give an insight onto my life of yogurt physicist, as I consider it my duty as a researcher to explain what scientific research is all about (and why it matters so much). The outreach events in which I have taken part so far are:


I graduated from ESPCI Paris in Physical Chemistry in 2015, after an exchange year at Politecnico di Milano in Materials Engineering. During my curriculum, I had working experiences both in research (project in fracture of hydrogels in microfluidic devices at EC2M, ESPCI Paris) and in industry (placement as a development engineer on specialty polymers at Arkema Kyoto Technical Centre). I started her PhD in 2015 at the School of Physics and Astronmy of the University of Edinburgh, in close collaboration with Unilever R&D Colworth, where I am based. My PhD is part of the EU-funded Innovative Training Network COLLDENSE(funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 642774).
