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)  Infrared multiphoton dissociation spectroscopy

5)  Studies of entropy effects in the kinetic method

6)  Proteomics studies of bacteriophages and mycobacteria

 

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

Image result for Thermo TSQ quantum ultra

Shimadzu UPLC – Thermo LTQ-XL with ETD

TSQ quantum classic triple quadrupole

2 LCQ DECA ion traps
