Davidson was born in 1961 in London. He obtained a B.Eng , B.Eng and M.Eng at the University of Pretoria. After completing his military conscription in the SANDF he worked at the CSIR in Pretoria, focusing mainly on defence electronics. In 1988 he was appointed Senior Lecturer at the Department of Electrical and Electronic Engineering at the University of Stellenbosch. He received his PhD from Stellenbosch University in 1991 with a thesis on parallel processing for computational electromagnetics. In 1992 he was appointed Associate Professor and from 1996, Professor. During his first sabbatical he was a Visiting Scholar at the University of Arizona, Tucson and worked with Richard Ziolkowski on computational electromagnetics techniques for applications in optics. During his second sabbatical he was Visiting Fellow Commoner at Trinity College, Cambridge and worked with Ronald Ferrari. He also worked with the Electricity Utilisation Group at the Engineering Department of Cambridge University, under Ricky Metaxas. The group worked on finite element methods for radio-frequency problems in electromagnetics. He visited the Delft University of Technology in the Netherlands, where he was hosted by Leo Ligthart as Guest Professor at the International Research Centre for Telecommunications-Transmission and Radar during his third sabbatical. He worked on time-domain Finite element method formulations applied to ground-penetrating radar. In 2009 his sabbatical took him to the University of Manchester. In 2017 he obtained a D.Eng from Stellenbosch University. In 2018 he joined the International Centre for Radio Astronomy Research at Curtin University, Perth, Australia. Davidson leads the engineering team at the Curtin Institute of Radio Astronomy with a focus on the international Square Kilometre Array radio telescope, as well as the Murchison Widefield Array. They are involved in research as diverse as antenna design and computational electromagnetic simulation and metrology.
Research interests
Davidson's initial research interests centred on computational techniques including the method of moments, finite-difference time domain and finite element methods. His work was focussed on the underlying theory and engineering applications of the methods. He was involved in the Computational Engineering special interest group of the National Centre for High Performance Computing. He was also involved in the MeerKAT and SKA projects. He was the principal investigator of the MeerKAT High Performance Computing for Radio Astronomy research project at Stellenbosch University, in collaboration with the University of Cape Town, the Centre for High Performance Computing at the CSIR and the MeerKAT office. Davidson's research at Curtin University focuses on radio astronomy and in particular on antenna design, computational electromagnetic simulation and metrology; radio frequency front ends; digital back-ends; instrument calibration; and interferometry.
Works
Davidson has published more than 50 journal papers and 100 conference papers. His book, "Computational Electromagnetics for RF and Microwave Engineering" was published in 2005 with a second edition in 2010.
