About
Ernest McGahee is a pioneering analytical chemist whose work centers on the development of high-throughput, sensitive methodologies for detecting environmental carcinogens in human biospecimens. His research primarily focuses on heterocyclic aromatic amines (HAAs)—potent mutagens formed during the cooking of protein-rich foods—and their role as biomarkers of dietary exposure and cancer risk. McGahee’s most cited work, a 2016 study published in *Analytical and Bioanalytical Chemistry*, introduced a groundbreaking approach that combines isotope-dilution liquid chromatography–tandem mass spectrometry (LC-MS/MS) with a robotic sample preparation system. This innovation dramatically improved the throughput and sensitivity of urinary HAA analysis, enabling the simultaneous quantification of multiple amines at parts-per-trillion levels. By automating extraction and cleanup, his method reduced manual error and processing time, making large-scale epidemiological studies feasible. With 11 citations, this paper has become a foundational reference for researchers investigating diet-disease links. McGahee’s contributions are instrumental in advancing precision exposure assessment, bridging the gap between laboratory chemistry and public health. His work exemplifies how rigorous analytical development can empower population-level investigations into the origins of cancer.
