The effects of Baltic-North Sea salinity transition on natural populations
It has been suggested that ecologically marginal environments harbour populations that experience extreme selection regimes and quite often these environments are also geographically marginal. The Baltic Sea, for example, is an extreme environment, geographically peripheral and ecologically marginal with low winter temperatures and permanently low salinities ranging from 1-2psu to 25psu. Populations inhabiting this area are therefore expected to experience life history changes that may influence their genetic set up.
I am mainly interested in the incidence of asexual reproduction in the Fucus vesiculosus – F. radicans complex across environmental gradients, particularly salinity conditions in the Scandinavian coasts.

Stock delineation and population structure in conservation of marine species
Advances in biotechnology have generated new techniques that can be applied to long-standing problems in fisheries. I am interested in using these innovative techniques and developing molecular tools to examine the long-term genetic integrity of species and to assess the stock structure of the marine resources.
Another critical question I am interested in is the identification of the origins and unique genetic entities in marine species. This information is vital in assessing the ranges and make-up of management units for their effective conservation.
