My research interests deals with the isolation, identification and analysis of low-molecular substances in medicinal plants or herbal products with the aim to find a rationale for traditional usage of the plant and/or to find new lead compounds from Nature. Ethnopharmacology is an important approach for the selection of plants. 

I am currently working on the following projects

  • Health effects of extracts and polyphenols from Nordic berries and medicinal plants.
  • Isolation and characterization of natural products from medicinal plants used against mental diseases
  • Plant.ID, molecular identification of plants
