Congratulations to Professor Peter Gill who has been awarded the 2019 David Craig Medal and Lecture, one of the Australian Academy of Science major awards.
Professor Gill has made both fundamental and applied contributions to the progress of quantum chemistry. His models for three-electron bonding and dication dissociation have been widely adopted by experimentalists. His developments in efficient two-electron integral algorithms, perturbation analysis, linear-scaling methodology, DFT functionals, the theory of excited states, and Coulomb-splitting techniques have all become mainstream tools in his community and, by implementing many of his ideas within his Q-Chem software package, he has ensured that his advances are rapidly translated to other areas of computational science, including pharmaceutical research and the design of new materials. His recent insights into electron correlation and the nature of the uniform electron gas are changing the underlying paradigms of density functional theory (DFT).
