About

I am a Master’s student in the Environmental Change and Global Sustainability programme at the University of Helsinki, specialising in Aquatic Sciences. I am interested in understanding how environmental change affects biodiversity and how research can support ecosystem conservation and management.

My current research examines how heatwave conditions affect interactions between bladderwrack and isopod grazers in the Baltic Sea coastal ecosystems, combining field sampling, laboratory experiments and ecological data analysis. I have also worked in terrestrial environments, contributing to forest conservation and management through the assessment of spider communities. Working across aquatic and terrestrial systems has strengthened my interest in species interactions, ecosystem functioning and ecological responses to environmental change.

🌊Grazing under pressure: Heatwave and wave-exposure of Fucus vesiculosus influence isopod grazing

How do marine heatwaves alter interactions between grazers and foundation species? My Master’s thesis combines field sampling and a laboratory experiment conducted at Tvärminne Zoological Station to investigate how warming and the habitat origin of bladderwrack affect isopod grazing. The findings will improve understanding of how temperature and habitat origin shape a key grazer–macroalga relationship and help predict heatwave-driven changes in Baltic Sea coastal food webs.
