My field of research concerns faunistics, especially with focus on crustaceans and can be divided in 4 major points:

1)   Lifecycle studies of barnacles and related crustacean groups have constituted a major part of my research activities. These animals are unique among crustaceans since they all, without exceptions, alternates between a free-living larva stage and an irreversible attached adult and detailed lifecycle studies have proved essential in attempting to understand their morphology, ecology and evolution. 

 

2)   Invasive species present an increasing threat to the marine environment in Norway and other places. Knowledge about the mechanisms enabling exotic marine species to invade new areas and the possible ways to prevent them from happening is an important field of marine research. In the recent years I have been studying the population dynamic and genetics of two invasive marine crab species and their most prominent parasite, a parasitic barnacle or rhizocephalan, which as adult castrates their crab hosts. The data from the study of these model systems will be used to evaluate if it is possible to control biological invasions in marine systems by the use of parasites. 

 

3)   Solid information about the phylogenetic relationships between living organisms is crucial in order to address relevant and correct biological questions. I am, therefore, interested in how to construct the most reliable phylogeny by the use of data from diverse data like dna, fossils and morphological and geographical sources.  My major phylogentic interest concerns the parasitic barnacles, Rhizocephala, but I am also occupied with other phylogenetic issues, especially within crustaceans. 

 

4)  With a maximum depth of over 1300m, the Sognefjord is the deepest fjord in the world. Extending inland over 150km, it provides a unique environment for studying dispersal and population connectivity of benthic marine fauna – research themes that are central to the understanding of biodiversity. The many side fjords to the Sognefjord are not as deep as the main fjord, and resemble, therefore, the majority of western Norwegian fjords.

So what is the dispersion between side fjords, does the deep main fjord provide a barrier and/or does the system involve a number of relatively “isolated” populations?

In addition, finding out what is actually living down there is an interesting exercise, since the benthic fauna of the Sognefjord is relatively unexplored and unknown.

These questions are addressed at frequent research cruises by employing classical sampling methodologies (bottom trawls, sledges and dredges), video based habitat and community mapping as well as molecular technologies.

 

As it appears from the research points above, the type of science I am conducting depends on methods and expertise from many areas of biological research. So despite that I, as a starting point, address questions originating in the classical morphology of marine organisms, the answers I look for rely totally on a multidisciplinary approach.
