We use mass spectrometry and high-level theoretical calculations to study the intrinsic properties of gas-phase molecules.  We have been studying the gas-phase acid-base properties of a variety of protein and non-protein amino acids using the extended kinetic method in an ESI- quadrupole ion trap mass spectrometer. In addition, we have been studying the effects of entropy on the dissociations of the proton-bound dimer ions that are used in extended kinetic method studies.   We have recently started to study the effects of non-protein amino acid incorporation on the thermochemcial properties and fragmentation pathways of small peptides.

We have two mass spectrometers in our laboratory, a Finnigan LCQ-DECA ion trap and a home-built flowing afterglow triple quadrupole instrument.  We are currently in the process of ressurrecting the FA-QQQ and will soon be able to use it for studying the kinetics of ion molecule reactions as well for determining absolute bond dissociation energies using energy-resolved mass spectrometry experiments.

Here are pictures of a quadrupole ion trap
