About Dr Roger David Dixon

A chemist and geologist by training, I am presently the manager of a mineralogical laboratory at the University of Pretoria.

Prior to this I was the manager of a very varied forensic laboratory, utilising a variety of disciplines and a range of sophisticated analytical techniques for the analysis of a wide range of materials, including explosives, gold, paint, soil, plants, oils and toxic waste. Here I held the rank of Colonel, and the post of Commander: Materials Analysis, Forensic Science Laboratory, South African Police Service.

My scientific expertise covers a broad range, and I am particularly good at investigative research and problem-solving. As a laboratory manager, I have been instrumental in setting up the present Materials Analysis laboratory over the past 10 years, acquiring and developing staff in a variety of disciplines.

I worked at the Forensic Science Laboratory from 1994 to 2012. Prior to that, I worked for the Geological Survey as a mineralogist and later was Curator of the Museum of the Geological Survey. I have published in excess of 50 articles and books, both locally and internationally, in the fields of geology, mineralogy, botany and history. In thirteen years I have conducted more than 1000 forensic investigations, in a number of disciplines, and have testified in South African courts as an expert witness in most of them.
