Teaching

Currently I am teaching: CHEM105 - Forensic Chemistry

Current research projects

Heat of formation of ketene

The fact that the relatively simple molecule ketene has several, wildly different values for its heat of formation in the literature is annoying, and I aim to try to fix that.

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.

Structure of NH₄NO₃ hydrates and solutions

Ammonium nitrate is an amazing compound with a wide variety of uses, from fertilizer to explosives. One of the amazing properties of this compound is its incredible miscibility with water. In saturated solution at room temperature there are approximately one water molecule for every ammonium and nitrate ion! I am applying state-of-the-art electronic structure calculations to study the structure of these mixtures.

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.
