Research Interests


We use mass spectrometry and high-level theoretical calculations to study the intrinsic properties of gas-phase biomolecules.  We are especially interested in the chemistry of so called “non-protein amino acids”, which are naturally-occurring compounds that are not coded by RNA. These species serve as model systems for us to understand the subtle interplay between structure and function in biological molecules.


Current projects in the lab include:


1)  Gas-phase thermochemistry of protein and non-protein amino acid using the extended kinetic method.

2)  Peptide fragmentation mechanisms

3)  Hydrogen-deuterium exchange of biomolecules

4)  Studies of entropy effects in the kinetic method

5)  Proteomics studies of bacteriophages


We have a variety of instrumentation in our lab, including:


LCQ ion trap


TSQ quantum classic triple quadrupole


Home-built flowing afterglow triple quadrupole


Quattro Ultima triple quadrupole
