Welcome to the Glish Group Home Page at the University of North Carolina at Chapel Hill. The members of our analytical chemistry lab are interested in a variety of areas of mass spectrometry. Our focuses include the use of the MSn capabilities of the quadrupole ion trap, gas phase ion chemistry, and application driven instrument development. We are also involved in the study of aerosol particles, peptide and protein chemistry. Research projects are quite diverse in the Glish group, from fundamental studies of ion energetics and dissociation to biomarker discovery. This page should serve as a guide to the work and interests of the Glish Group, including a list of publications and a "What's New" section to share what we have been up to lately. Make sure to check out the Photo Gallery to put faces with names of the present and past members of the group.
