Secondary metabolites of marine and freshwater algae – their isolation, purification and detection. 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 microcystins, okadaic acid, pinnatoxins, ciguatoxins and azaspiracids.
