About

Dr. Julia Humphries is a pioneering lipidomics researcher whose work has fundamentally advanced our understanding of cardiovascular disease at the molecular level. Her primary research areas encompass lipid biochemistry, atherosclerosis, and mass spectrometry-based metabolomics. Dr. Humphries’s most significant contribution came from her landmark 2011 study, “Comparative Lipidomics Profiling of Human Atherosclerotic Plaques,” which has garnered over 210 citations. In this seminal work, she adapted a chip-based robotic nanoelectrospray platform interfaced with a triple quadrupole mass spectrometer to perform the first systematic, comprehensive lipid analysis of human atherosclerotic plaque tissue. This methodological innovation enabled the identification and quantification of hundreds of lipid species directly from tissue sections, revealing distinct lipid signatures associated with plaque vulnerability. Her findings provided critical insights into the lipid-driven mechanisms of plaque rupture, the primary cause of heart attacks and strokes. By bridging cutting-edge analytical chemistry with clinical pathology, Dr. Humphries established a new paradigm for studying lipid metabolism in disease, paving the way for novel diagnostic biomarkers and therapeutic targets in atherosclerosis.
