Peter Malcolm Wallace Gill (born 9 November 1962) is a New Zealand theoretical and computational chemist known for his contribution to density functional theory (DFT). He is an early and main contributor to the computational chemistry software Q-Chem and was the president of the company during 1998–2013. He is especially known for developing the PRISM algorithm for evaluating two-electron integrals and linear-scaling DFT, as well as self-consistent field method for excited state electronic structure.

Education and career

Gill was born in Auckland and received his BSc in 1983 and MSc in 1984 from the University of Auckland. He received a PhD in 1988 from the Australian National University under the supervision of Leo Radom. During this time, he investigated hemi-bonding and the convergence of perturbation theory in quantum chemistry. After graduation, he conducted postdoctoral work with John Pople at Carnegie Mellon University from 1988 to 1993. Following this stint, Gill accepted a lectureship at Massey University in 1993. He became a lecturer at the University of Cambridge in 1996. In 1999, Gill became the inaugural chair of theoretical chemistry at the University of Nottingham. He moved to Australia and became a professor at the Australian National University in 2004 and later moved to the University of Sydney in 2019 as the Schofield Chair in Theoretical Chemistry.

In 2001, Gill wrote an essay pronouncing the demise of density functional theory thanks to the rise of hybrid functionals for exchange interactions between electrons.

Honors and awards

Gill is the president of the World Association of Theoretical and Computational Chemists (WATOC) and received the Dirac Medal in 1999 and the Schrödinger Medal in 2011 from WATOC. In 2013, Gill received the Fukui Medal from APATCC. Gill was elected a Fellow of the Australian Academy of Science in 2014 and received the David Craig Medal from the Australian Academy of Science in 2019. In 2015 Gill was inducted to the International Academy of Quantum Molecular Science.
