Research Focus

Metabolomics and Mass Spectrometry

Our lab is developing mass spectrometry-based technology for unbiased comparative analysis as well as the structural and biological characterization of metabolites. These developments include nanostructure-based mass imaging, novel data analysis software, as well as a unique database to facilitate metabolite identification. Our XCMS software, a metabolomics LC/MS data analysis approach, has been widely applied (with over 20,000 downloads) for alignment and statistical data LC/MS analysis. XCMS is also coupled with Metlin, a database of metabolites and MS/MS data used to facilitate metabolite identification and classification. Our nanostructure-based mass spectrometry platform, a novel matrix-free surface analysis technology, is being developed for metabolite tissue imaging, activity screening and analyzing nano-arrays.
