What affects population dynamics in seabirds, and which role do climatic variations play in this context? This is the main scientific question I am currently working on. Drawing on results of life history theory and evolutionary ecology, and utilising long-term datasets, I test whether demographic and ecological covariates can account for interspecific differences in climatic responsiveness. These studies are nomothetic in nature, and are carried out in a (phylogenetic-)comparative framework. In addition I am involved in detailed (idiographic) case studies of the seabird colony of Hornøya in northern Norway.

Evolutionary biology constitutes my second main professional interest. Besides using comparative analyses in some of my ecological studies, I have contributed to developing such phylogenetic-comparative methodologies. Although my interest in macroevolution and phylogenies has so far been more on a spare time basis, it has resulted in a couple of popular accounts and a text book (in Norwegian).

Many of my other interests lie in the area of intersection between ecology, society, evolution and philosophy. For example, I have written a couple of articles, most of them in Norwegian, about environmental ethics, ontology of biology, evolutionary feminism, evolutionary ethics, philosophy and history of biology.
