Personal profile

Artistic and research interests

My research concerns novel biobased materials, especially ways to produce fibres from nanocellulose by wet-spinning. With this kind of technique, textile fibres could be made from forest resources with new properties, such as controlled porosity and strength. In order to optimize the method, I study also nanocellulose rheology (i.e., flow behaviour) and water interactions, which critically affect the qualities of the wet-spun fibre. I aim to participate enabling the societal transition towards a circular economy by developing biodegradable fibre materials competitive with oil-based ones.
