PhD student

I am a Marine Biologist with a great interest in macroalgae physiology and seaweed aquaculture. My passion for seaweed drove me for the last 5 years, seeking for seaweed industry sector sustainability, through smart optimization of culturing methods of multiple commercial interest species. I am interested in industrial applied research, always looking for new challenges, collaborate with new teams, learn new techniques, acquire and share knowledge. 

In my PhD, I will test and develop new substrate materials and binders suitable for seaweed culturing.

I enjoy travelling, hiking, swimming in the ocean and playing team sports (especially volleyball).

Material development for global seaweed cultivation

This PhD will explore how settlement, development and attachment of north Atlantic seaweeds are influenced by the surface characteristics, focusing on the rhodophytes Palmaria palmata and Porphyra spp.  The influence of the environmental factors, substrate material chemistry and structure will be assessed combining both laboratory with coastal seaweed farm trials (measuring algal growth, juvenile attachment rates and epifloral analysis). This research will aid in the development of novel cultivation substrates for the global seaweed industry.

The industrial partner and funder, W.L. Gore & Associates Ltd, will provide this project the knowledge and support to choose and design suitable substrate material for seaweed production.
