Prof. Andrzej Wasik is an analytical chemist with over two decades of expertise in trace analysis, food safety assessment, and environmental contaminant detection. His research focuses on developing advanced analytical methodologies for detecting adulteration, emerging contaminants, and quality threats in complex food matrices using high-performance chromatography coupled with tandem mass spectrometry, including LC-MS/MS, GC-MS, and spectroscopic techniques. Key research interests include food authentication through chemical fingerprinting and compositional profiling, detection of endocrine disruptors such as bisphenol analogues and pharmaceuticals in food products, trace analysis of emerging contaminants at ultra-low levels, sample preparation optimization using solid-phase extraction and green chemistry principles, volatilomics for real-time quality monitoring, and method development and validation for regulatory compliance. With publications spanning analytical chemistry journals including Analytical and Bioanalytical Chemistry, Journal of Chromatography A, Food Chemistry, and TrAC Trends in Analytical Chemistry, he brings extensive expertise to advancing next-generation detection strategies for food fraud, adulteration prevention, and consumer health protection through scientific innovation.
