Per Åberg, professor i marin ekologi

Area of Specialization:

Population ecology, Demography

Research:
My key qualification is in the field of population ecology using both experimental and quantitative modelling approaches. During the last years I have also been involved in research within the fields of population genetics and rocky shore community ecology. Main field of interest is in basic research in demography and life history evolution with applied aspects in biodiversity and conservation biology.
