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

 
Background
Master’s degree in analytical chemistry from the University of Kiev, Ukraine. Master’s degree in food safety from the Norwegian School of Veterinary Science Oslo/Norway. Professional experience from numerous projects and studies in the field of mycotoxin analysis, incorporating both method development and extensive work with quality assurance and statistics. 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.
