Her dissertation, “Fouling of macro epibionts on cultivated Saccharina latissima (Phaeophyceae) — In situ temporal and spatial variation,” examines fouling organisms on cultivated sugar kelp, documenting their extent, species composition and seasonal dynamics along the Norwegian coast.

She has worked with multiple life stages of cultivated kelp and first developed her expertise in marine macroalgae during her master’s degree in marine biology and aquaculture at the Norwegian University of Science and Technology (NTNU) in 2013, where she focused on optimising gametophyte cultures. Sanna has shared her research through international publications, university teaching, school outreach activities and conference participation.

She joined Møreforsking in January 2022 and is part of the Sustainable Oceans and Coasts research group. Her research interests centre on the cultivation of various marine species, with a primary focus on macroalgae.
