Unraveling the
metabolic basis
of human cancer.

I'm Fouad Choueiry, PhD, a metabolomics scientist and bioanalytical chemist specializing in cancer metabolism and human disease. I completed my doctoral studies at The Ohio State University in March 2024 within the Zhu Lab at the James Comprehensive Cancer Center, where I developed and applied high-resolution mass spectrometry tools to understand how cancer rewires human metabolism.

My research spans targeted and untargeted LC-MS/MS metabolomics, real-time volatilomics via SESI-HRMS, and multi-omics data integration — connecting metabolome alterations to transcriptomic signals to identify disease mechanisms and actionable biomarkers. I've applied these approaches across colorectal cancer, non-Hodgkin lymphoma, lung cancer, and drug resistance biology.

I'm now based at UC Berkeley, continuing to advance metabolomics methods at the intersection of analytical chemistry and disease biology.

My current work extends into emerging frontiers of the field: the development of protein binding assays coupled with mass spectrometry to characterize small molecule–protein interactions at biochemical resolution, subcellular metabolomics to map metabolite distributions across organelle compartments, and single-cell metabolomics — pushing the sensitivity limits of mass spectrometry to resolve metabolic heterogeneity at the level of individual cells, with direct implications for understanding tumor microenvironments and cell-state transitions in disease.

I approach science as an interdisciplinary bioanalytical chemist — equally at home building wet-lab LC-MS methods and developing computational pipelines to extract biological meaning from complex, high-dimensional metabolomics data.
