Research in Computational Chemistry

Dr. Lovitt’s doctoral and post-doctoral research used computer modeling to explain and predict the reactivity of organic and organometallic complexes. Using Density Functional Theory (DFT) bonding analysis tools like energy decomposition analysis, we can predict the reactivity of methane and hydrogen with transition metals which helps speed up the process of making these molecules in the lab.  Bond analysis tools like energy decomposition analysis (EDA) and atoms in molecules (AIM) build an atomic picture of bonds, which helps explain why some molecules are more stable than others.  This work can help in the creation of better catalysts for green energy production.

Current work in computational chemistry is limited to  occasional undergraduate research projects done in partnership with colleagues at local institutions.
