About me

  • My research is about receptor-mediated toxicity, prevention and health risk assessment.


  • My research generates data, which is used to support national and international health risk assessment work in the areas of persistent organic pollutants and other health hazardous chemicals. The studies aim to clarify the molecular mechanisms of action, identify critical effects and effect levels, and to establish safe exposure levels for humans. Such knowledge is needed to develop specific and sensitive effect- and exposure markers, which in turn, can be used to improve the possibilities to establish casual relationships in human studies, and also to develop specific and sensitive test methods within the health based risk and safety control of various categories of chemicals.

    The experimental research in my group focuses on receptor-mediated toxicity and its consequences on hormonal and metabolic pathways. I have, since long, a particular interest in the retinoid system and it´s crosstalk with the Ah-receptor both in normal and toxicological situations. Disease categories that are relevant for my research include bone and vascular abnormalities, cancer, fertility problems, behavioral influences and different types of metabolic disorders. Right now, we use different model systems to clarify how different types of chemicals interfere with bone development and homeostasis.
