Danie matriculated in 2003 from Jan van Riebeeck High school in Cape Town. He received distinctions in Afrikaans, English (both first language), Science, Computer Science, Geography and Mathematics (all high-grade). He graduated in 2007 from Stellenbosch University with a B.Eng. (Cum Laude) in Electrical and Electronic Engineering with additional Computer Science subjects. In 2009 he completed his MScEng (Cum Laude) from the same institution. During the course of his studies, Danie received distinctions in 43 out of 44 undergraduate modules, including his final year project entitled Focal Plane antennas for the Square Kilometer Array. For this, he was nominated as one of four finalists in the 2007 M-Net Jak van der Merwe Competition for Innovation.

For his MScEng, Danie focused on the development of a Focal Plane Array feed-structure for parabolic dish reflector antennas for the Square Kilometer Array (SKA) and the Karoo Array Telescope (KAT). Thereafter, he pursued his PhD (part-time) while working at Altair Development S.A. (Pty) Ltd (previously EM Software & Systems – S.A. (Pty) Ltd.) in Stellenbosch, South Africa, as a senior software developer for the commercial computational electromagnetic (CEM) software package, FEKO.

His PhD research was focused on the development of efficient numerical analysis techniques for the analysis of finite antenna arrays. During this period, Danie developed a domain decomposition based technique called the Domain Green's Function Method (DGFM) that is now included in FEKO.

During his post-graduate studies, Danie formed part of the computational electromagnetic (CEM) research group of Stellenbosch University (CEMAGG) under the leadership of Prof. D.B. Davidson. His research interests include electromagnetic modelling, high performance computing (HPC), parallel programming, antenna design and energy efficiency, and characteristic mode analysis.

In 2011 Danie co-founded a creative web development firm called Webfront Creative Design that now forms part of RMS Engineering (Pty) Ltd. who provides a variety of consulting engineering, software and application development services to a wide audience.

From 2015 to 2017 he did a postdoc at Stellenbosch University focussed on the use of High Performance Computing for Radio Astronomy purposes. From July 2017 he holds a lectureship position at the Department of Electrical and Electronic Engineering at the same institution.

Danie is married to Sunel Ludick and together with their two children, they reside in Somerset West, South Africa. He is also a keen mountain biker, trail-runner and golfer.
