Abraham Kuri Cruz is an analytical chemist specializing in liquid chromatography–tandem mass spectrometry (LC–MS/MS), untargeted metabolomics, and the characterization of complex biological matrices. His research focuses on high-resolution LC–MS/MS analysis of small molecules in human serum, plasma, urine, and stool.
Abraham has conducted research at the National Institute of Standards and Technology (NIST) since 2018, initially through a six-month research stay focused on the LC–MS/MS characterization of urine candidate reference materials. He later returned to continue this work and now supports NIST research through the PREP program in affiliation with Georgetown University. His work includes the characterization of human biofluid and stool reference materials, quality-control assessment, data analysis, technical documentation, and collaborative multi-platform metabolomics studies. He also contributes to data resources for mass spectrometry–based suspect screening of pyrrolizidine alkaloids in dietary supplements.
Abraham’s technical experience includes Thermo Q Exactive Orbitrap and Ultimate 3000 LC systems; HPLC/UPLC; sample preparation using protein precipitation, liquid–liquid extraction, and solid-phase extraction and data processing with MZmine, MS-DIAL, MS-FINDER, and MetaboAnalyst.
