Chem. 103 General Chemistry Chem. 301, Quantum Mechanics/Spectroscopy Chem. 309, Principles of Instrumental Analysis (Fall 2021) Chem. 404, Advanced Analytical Chemistry Chem. 408 Computational Chemistry Chem. 456 Mass
Spectrometry (Spring 2022) 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 peptides 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:
