Research interests

Isolation, purification and identification of secondary metabolites from fungi and plants. Mechanistic studies of natural toxins in bioassays.


Master’s degree in analytical chemistry from the University of Kiev, Ukraine. Master’s degree in food safety and Dr. philos. in chemistry and toxicokinetics from the Norwegian School of Veterinary Science Oslo/Norway. Professional experience from numerous projects and studies in the field of mycotoxin analysis. Identification, isolation and structural characterisation of unknown bioactive compounds (LC/MS, preparative HPLC, MSn fragmentation and high-resolution mass spectrometry) and implementation of in vitro methods for evaluating toxicity, absorption and biotransformation of toxic substances are main subjects of expertise. Member of the working group for biotoxins (WG5) under The Technical Committee 275, “Food analysis-Horizontal methods”, within the CEN system (2005-2010). Scientist at the Norwegian Veterinary Institute since 2006.
