Teaching

Currently I am teaching:

• CHEM105 - Forensic Chemistry
• CHEM328 - Science Seminar

Current research projects

Spectroscopic properties of tyrosinate and tyrosyl

Photosystem II contains a tyrosine residue that is thought to play a key role in the overall action of this amazing structure. I am applying my computational expertise to help Dr. B. A. Barry at Georgia Tech interpret her group's experimental results.

Triazine and other interesting N₃H₃ species and derivatives

I began my training as a computational chemist as an undergraduate at Moravian College under the direction of Dr. Carl Salter investigating this fascinating system.

Calculation of accurate gas phase basicities of small biological molecules

This on-going collaboration with my Professor Darrin York and his group at the University of Minnesota seeks to compute accurate gas phase basicities and proton affinites of small bilogical molecules, especially those involved in phosphate-hydrolysis, in order to better understand and model these species.

Electron Energy Analysis

Professors R. D. Libby and O. C. Salter at Moravian College are developing an interesting new paradigm for teaching organic chemistry.  I am performing quantum chemical calculations to provide a connection between accurate electronic structure and the qualitative valence bond model used in their Electron Energy Analysis method.
