Effects of marine heatwaves on canopy forming seaweeds and marine forests (PhD 2019)
My research will focus on effects of marine heatwaves on the dominant canopy forming seaweeds along the Western Australian coastline: Ecklonia radiata and Scytothalia dorycarpa. The research will focus on different characteristics of heatwaves, effects on different ontogenetic stages and contrasting responses of seaweed populations from different localities to determine the importance of timing and parental thermal history. In combination, this will lead to a better understanding of the response and resilience of marine forests to future heatwaves.
I completed first a Bachelor of Science in Biology with main focus on marine biology at the University of Bremen (Germany) in 2011. Afterwards I started my master studies in the EMBC (Erasmus Mundus Master of Science in Marine Biodiversity and Conservation) program at the University of Bremen (Germany), University of Oviedo (Spain) and University of Algarve (Faro, Portugal) which I completed in 2013. My research during both studies involved the impact of ocean acidification on a calcifying marine red alga (Corallina officinalis), and the interaction between gorgonians and seaweeds under ambient and acidified conditions in temperate waters. Afterwards I gained experience in coral reef surveys during my Marine Protection Internship with Shallow Waters in Cambodia in 2013.
