The current focus for my research group is to lead exploratory investigations using high accuracy electronic structure and electron transport techniques to uncover new and more efficient molecular devices for electronics and renewable energy applications. To do this, my research group develops and employs novel Green’s function transport formalisms combined with both traditional wavefunction based electronic structure methods and a unique type of electronic structure methods based on 2-electron reduced density matrix (2-RDM) mechanics which provide a more natural picture of electron interactions. These techniques allow us to examine promising molecular electronic devices in order to better define the role of molecular electron-electron interactions in determining electron transport and provide experimentalists with useful feedback for the challenging task of designing new devices. Other interests include organic materials/electronics and studying small molecule and organic reaction pathways using high accuracy electronic structure and molecular dynamics techniques.
