Molecular Scattering: Development and application of the coupled-channel method for inelastic collisions in atom-molecule systems. Pioneered the use of ab initio potential energy surfaces for molecular scattering applications. Established benchmarks for scattering matrices for inelastic molecular collisions.
Electronic Structure: Development and application of the quantum Monte Carlo (QMC) method to atomic and molecular systems. Developed computational approach for the QMC calculation of molecular properties whose operators do not commute with the Hamiltonian. Introduced new compact integral formulation for correlated gaussian functions.
