Associated professor in Ecosystem based fish management. My research spans several interlinked themes in aquatic ecology, fish biology, and sustainable resource management to understand how environmental change, human pressures, and ecological interactions affect aquatic communities.

Presentation

I am appointed as collaboration specialist at SLU aiming to bridge science and natural resource management through collaboration, new innovations, environmental monitoring, and governance. I work with small scale fishers, water-owners, NGOs, authorities, and private actors to co-develop sustainable solutions. My emphasis is on holistic approaches from data collection and environmental monitoring to evaluation and knowledge transfer — aiming to inform sustainable use and policy.

 

Research

Ecosystem-based and multi-use management of aquatic resources.

Investigating changes in coastal and pelagic food-webs under eutrophication and altered predator/prey dynamics — and how these affect stability and biodiversity in aquatic habitats. 

Developing practical and collaborative measures to restore/rehabilitate aquatic ecosystems and promote sustainable fishing. Especially studying impact of reed harvesting in eutrophic coastal waters to extract excess nutrients (phosphorus) and support ecosystem restoration. 

 

Eco-evolutionary dynamics of fish populations under environmental change.

How do factors like fishing pressure, climate change, and eutrophication influence life-history traits like growth, size, reproduction, and population structure over time?
