Contributions to Gaussian: Methods for thermochemistry including G1, G2, G3 and CBS; Post-SCF method development including CCD, QCISD, QCISD(T) and CCSD(T); Derivative methods including early implementations of HF 2^nd derivatives and MP2 and CISD gradients; CIS(D) for excited states.

Research Interests

Our research group focuses on new developments in electronic structure theory along with challenging applications to investigate the structures and properties of molecules and materials. The work is collaborative and multidisciplinary covering the areas of chemistry, physics, and materials science.
