The mixture complexity, dynamic range and diversity of transcriptional, translation and post translational modifications associated with protein expression, as well as the complex array of specific protein-protein interactions involved in the regulation of cellular function, presents a significant analytical challenge to mass spectrometry (MS) based proteomic methods employed for characterization of the hitherto unknown functional role of the thousands of genes identified from recent genome sequencing initiatives.

Research in our laboratory is broadly directed toward the development and application of novel mass spectrometry based chemistries and instrumentation to address these challenges. Aspects of this research include:
(i) systematic examination of the fundamental gas-phase ion chemistries of amino acids, peptides and proteins in order to determine the mechanisms and other factors influencing their fragmentation reactions;

The presence of post-translationally modified (PTM) amino acid residues within a peptide sequence often has a dramatic effect on the fragmentation behavior of its protonated ions under low energy collision induced dissociation (CID) tandem mass spectrometry (MS/MS) conditions. MORE
