About me

My research focuses broadly on understanding the causes and consequences of biodiversity and ecosystem structure, from genes to seascapes. Most of my projects bridge fundamental and applied questions in community and ecosystem ecology, and uses coastal benthic ecosystems (seagrass beds, coral reefs, mussel beds, etc.) as a model.

I am particularly interested in three themes:

i) the relative importance of biodiversity and biotic interactions for ecosystem resilience to disturbance and environmental change,

ii) the role of organisms, particularly marine foundation species and mobile consumers, for ecosystem services and human well-being,

iii) how to optimize natural resource management and nature-based solutions to sustain biodiversity and ecosystem services in a rapidly changing world.

I lead a research group currently consisting of two PhD students (Benjamin Jones, Åsa Nilsson Austin) and two postdocs (Dr Agnes Olin, Dr Line Holm Andersen - starting May 1, 2021). I also co-supervise two PhD students (Sven Iburg, Johann Stiepani).

I have previously supervised two PhD students to finish (Dr Elisa Alonso Aller, Dr Angelica Chirico), three postdocs (Dr Serena Donadi, Dr Tiina Salo, Dr Candace Newman), co-supervised five PhD students (Dr Filip Svensson, Dr Sieglind Wallner-Hahn, Dr Hanna Oscarsson, Dr Linda Eggertsen, Dr Maria Eggertsen), and supervised >30 MSc students.


Teaching is both fun and stimulating, and I teach on several courses:

- Management of Aquatic Resources in the Tropics 15hp (course leader)

- Tropical Marine Biology 7.5hp (course leader)

- Ecology II 15hp (lecturer)


Student/postdoc supervision

I regularly supervise BSc (kandidat), MSc (master) and PhD (doktorand) projects, and mentor postdocs, in subjects relating to my research interests. If you are interested in doing your thesis or postdoc with me, please read my supervisor philosophy, email me and we'll book a first meeting!
