Academic career

From 1981 to 1983, Becke was a NSERC Postdoctoral Fellow at Dalhousie University. He took up his first faculty position at Queen's University in Kingston, Ontario in the 1980s. In 2006, he relocated to

to serve as the Killam Chair in Computational Science.

Research

Becke contributed in the development of non-LCAO, grid-based numerical methodologies for molecular orbital calculations. He was also contributed in the development and benchmarking of exchange-correlation functionals in Kohn-Sham density-functional theory. He is known for his highly cited work on the density-functional theory of atomic and molecular structure.

(DFT) was originally designed to describe metallic solid state systems. Becke, along with his co-researcher John Perdew, demonstrated that DFT could be an effective tool in quantum chemistry as well, where it is used to describe the structure and energetics of molecules. He developed a valuable computational technique (NUMOL) which allowed a new level of precision. His work has led to advancement in many areas of chemistry and physics, where his methods are used to calculate the molecular properties of large and complex molecular systems with greater accuracy. He was a developer of the theory of the
