Research interests

Method development concerning immunossays for detection of cyanotoxins/microcystins. Special interest in development of antibodies to recognise the metabolites and using the antibodies to developing immunological methods for detecting metabolites in food such as shellfish for the marine algal metabolites and in water for the freshwater algal metabolites. Especially interested in cyanotoxins/microcystins, okadaic acid and azaspiracids.

Background

Master’s degree in inorganic chemistry at Norwegian Institute of technology (NTH) Trondheim, Norway,1989. Method development, validation, quality assurance and accreditation for methods such as different techniques of atomic absorption spectroscopy and immunological methods for detection of food allergens.

Ongoing projects

Rotenon

Alfakloralose

Measurement of Cs-137 in food and feed (directed by Norwegian Food Safety Authority and Norwegian Radiation Protection Authority)
