Research and teaching associate, assistant professor in the Department of Chemistry, Faculty of Medical Sciences in Zabrze, at the Medical University of Silesia in Katowice, Poland. Scientific interests: analysis of food (mainly meat) and environmental (water, sewage sludges, and airborne particulate matter) and biological (urine and blood serum) samples; and the determination of compounds harmful to health and their metabolites, including polycyclic aromatic hydrocarbons (PAHs), their nitrogen and oxygen derivatives (nitroarenes and azaarenes), heterocyclic aromatic amines (HAAs), acrylamide, oxycholesterols, phthalates, nicotine, and cotinine. Analytical techniques applied: HPLC-DAD, HPLC fluorescence detection, GC–MS, LC–MS, solid-phase extraction, and solid-phase microextraction.
