Research interests

My research has focused on oxidative stress, aquatic ecotoxicology and environmental pollution. I am a member of the Fish Ecotoxicology group at the department of Biological and Environmental Sciences, and the EGO (ecotoxicology from gene to ocean) research platform. I am also active within the NICE projektet (Novel instruments for effect based assessment of chemical pollution in coastal ecosystems and have work as a post doctor in the MistraPharma (Identification and reduction of environmental risks caused by human pharmaceuticals) project.

I am currently leading a research project aimed at defining the effects of microplastic pollution on fish, "A sea of plastic – are plastic particles toxic to fish?", that is funded by Formas. This project will address effects of both the microparticles as well as associated chemicals.

I am also interested in researching the role of oxidative stress in physiological aging. Fish are very interesting models for studies of the aging process since species age in very different manners including rapid aging (i.e. pacific salmon exhibit rapid senescence and sudden death after spawning), gradual aging (which is most like our own, and seen in guppies, Japanese medaka which continue to grow, though at decreased rates, throughout their life span) and possible negligible aging (i.e. carp and rockfish shown indeterminate growth with no increased mortality).

I have addressed questions of aging, oxidative stress and telomere length in several models.

  • the growth hormone transgenic coho salmon, the effects of rapid  growth on oxidative stress and physiological aging; research partners – Jörgen Johnsson, Robert Devlin, Joachim Sturve
  • the Atlantic cod fish, which displays evolutionary changes in life history patterns resulting from commercial fisheries, as well as gender dependent aging patterns; research partners – Helen Nilsson Sköld
  • the Trinidad guppy, where life history evolution has occurred as a result of predators; research partners – David Reznick, Joachim Sturve.
  • oxidative stress and aging in arm regeneration in seastars; research partner - Helen Nilsson Sköld
  • telomere length in clonal organisms including clonally reproducing seastars and corals; research partner - Helen Nilsson Sköld.
