Dr. Andrew Percy is the Senior Applications Chemist for Mass Spectrometry. His responsibilities minimally involve overseeing product development, identifying new product market opportunities, assisting in the analysis of products for MS ‘omics applications, and providing technical support to customers.

Andrew has been in the MS field for more than 10 years. His main focus in his previous research was in the areas of structural and quantitative proteomics. In the former area, he developed several analytical methods to structurally interrogate binary multicomponent complexes (i.e., protein-ligand and protein-protein) through the use of novel bottom-up hydrogen/deuterium exchange mass spectrometric (H/DX-MS) approaches and novel data analysis strategies (e.g., minimalist and surogate approaches). In quantitative proteomics, he developed and applied an array of novel technologies for the targeted and multiplexed quantitation of candidate disease protein biomarkers in human/mouse biosamples. This research experimentally involved a bottom-up LC-MRM/MS approach with isotopically labeled peptide standards, while the analyzed biosamples encompassed invasive (e.g. human cerebrospinal fluid), minimally invasive (e.g. human/mouse plasma), and non-invasive (e.g. human urine and saliva) matrices. Overall, Dr. Percy has published more than 40 articles in peer-reviewed journals, acts on the editorial board of the Journal of Proteomics and Genomics, and serves as a regular ad-hoc review for a number of journals.
