I started my academic studies at Uppsala University, where I defended my thesis in Limnology in 1991. I have worked as a fisheries scientist since 1992 at Coastal Laboratory in Öregrund and at the Institute of Marine Research in Lysekil within the Swedish Board of Fisheries (lately at the Swedish University of Agricultural Sciences). I also work as a scientific coordinator at the Swedish Institute for the Marine Environment (SIME) since 2010. I am associate professor since 2009 in Marine ecology at Gothenburg university.
My research interests concerns fish behavioural ecology, for instance effects of migration on population separation and connectivity. I have studied especially the ecology and biology of Atlantic cod and European eel. I have studied the demersal fish population mosaic along the Swedish west coast by conducting trawl and egg surveys combined with tagging and genetics and otolith chemistry. Due to the effects of gear selectivity on the dynamics of Baltic Sea cod, studies on Baltic cod growth is of great concern. Historical developments of fisheries and fish stocks is another area of great interest. I have initiated collaboration work with economists, sociologist and jurists as to develop and investigate concepts such as ecosystem based fisheries management. I have also a long experience in fisheries management and international stock assessments.
The Baltic Sea ecosystem and marine life are exposed to many different impact factors at the same time. The BalticCAT research project further develops a food web model that will calculate the effects of a large number of natural and human impact factors.
The project evaluates whether Baltic cod food intake and metabolism have varied the last 85 years, similar to what recent findings suggest. It also explores how trophic level may have changed over the last 85 years by analysing ∂15N in archived otoliths.
In the project Pilot Stockholm Archipelago, the aim is to through local involvement develop and test a management model for regional ecosystem-based marine management that will help achieve the Swedish environmental objectives.

The BalticHER-project studies the population structure of locally spawning herring on the Swedish east coast. The study will evaluate by cross-checking genetical and otolith chemistry methods whether natal homing is a population structuring mechanism.
This research project studies the herring spawning activity in the Stockholm Archepelgo in relation to population structure and integrity, by measuring the density of herring larvae during the spawning period.
