Research:

Our research focuses on the development of mass spectrometry (MS) methods for the structural characterization of biomolecules. Specifically, we are interested in developing radical driven fragmentation methods that are amenable to the Fourier-transform ion cyclotron resonance (FTICR) mass spectrometry. One such method is electron capture dissociation (ECD). Unlike conventional ergodic fragmentation methods, ECD retains labile modifications in proteins and is well suited for post-translational modification (PTM) analysis. ECD and other electron activated dissociation (ExD) methods have also shown great promises in detailed structural analysis of glycans.

Our present research efforts also include the application of MS techniques to solve biological problems, such as protein deamidation, which is implicated in protein misfolding diseases and aging, and protein S-palmitoylation, which plays an important regulatory role in protein trafficking, membrane localization, and cellular signaling. Other current research projects include the implementation of vacuum ultraviolet photodissociation (VUVPD) in FTICR MS, the development of ion mobility spectrometry (IMS)-ExD-MS/MS method for isomer analysis, theoretical investigation of the glycan ExD mechanisms, and the development of bioinformatics tools for interpretation of complex glycan ExD spectra (collaborative work).
