About

Andrew N. Hoofnagle is a leading figure in clinical mass spectrometry and proteomics, with a focus on advancing the precision and throughput of protein quantification for diagnostic applications. His major contributions center on developing robust, high-performance liquid chromatography (HPLC) and mass spectrometry methods that bridge the gap between research and clinical practice. Notably, his work on the automated trapping column exchanger for nanoflow HPLC (2017, 5 citations) addresses critical bottlenecks in instrument reliability—such as fitting fatigue and column failure—enabling higher throughput and reproducibility in sensitive analyses. This innovation has practical implications for clinical labs, where consistent, high-sensitivity detection is essential. Hoofnagle’s research has been instrumental in standardizing protein measurement, particularly for endocrinology and toxicology, and his efforts have earned him recognition as a leader in translating complex proteomic technologies into routine clinical use. His work continues to shape how mass spectrometry is applied to improve patient care, making him a key resource for students and researchers interested in the intersection of analytical chemistry and medicine.
