His most important contribution is the introduction of the gradient method in quantum chemistry. This allows the prediction of the geometric structure of a molecule using computational chemical programs to be almost routine. He is the main author of the PQS computational chemistry program.
Among many honours he was made a Foreign Member of the Hungarian Academy of Sciences in 1993. He is a member of the International Academy of Quantum Molecular Science
