About
Yelena Sapozhnikova is a prominent analytical chemist whose research focuses on food safety, residue analysis, and the development of high-throughput multi-residue methods for detecting pesticides, veterinary drugs, and environmental contaminants in food matrices. Working primarily with complex animal-derived foods such as catfish, beef, meats, poultry, and tilapia, Sapozhnikova has pioneered innovative analytical approaches that simultaneously screen hundreds of chemical compounds at regulatory levels set by both U.S. and European Union standards. Her most celebrated contributions include the development and validation of sophisticated "mega-methods" combining ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS) with low-pressure gas chromatography–tandem mass spectrometry (LP-GC-MS/MS), capable of detecting over 300 compounds in a single analytical workflow. Her landmark two-part mega-method series published in 2020 garnered nearly 120 combined citations, reflecting their significant influence on food safety laboratories worldwide. Her 2018 study on meats and poultry has accumulated 52 citations, while her 2022 validation of the QuEChERSER mega-method for tilapia further demonstrates her commitment to expanding analytical coverage across diverse food commodities. Sapozhnikova's work has meaningfully advanced global food monitoring capabilities, making safer, more efficient residue surveillance increasingly achievable.
