I am a specialist crop scientist, with a particular interest in weed control. I hold BSc (Agric)(Plant Production), BSc (Agric.)(Honours) (Agronomy), MSc (Agric.) (Weed Science), and PhD (Agronomy) degrees from the University of Pretoria. During my studies and my career to date, I have received 7 academic awards, including academic honorary colours from the University of Pretoria. I have also been honoured by the awarding of a Fellowship of the Southern African Weed Science Society, and the Dave Aneke research award for outstanding research in the field of weed science.

Knowledge from research must be transferred to stakeholders, or it remains no more than an abstract idea, and publications or talks at symposia assit in this regard. To date I have authored in excess of 30 peer reviewed scientific articles, as well as more than 150 consultancy reports for various stakeholders in the Agricultural Industry.  In addition to these written reports, I have delivered more than 75 papers at national conferences, and 34 at international conferences, including 12 invited and 2 keynote presentations. I have also presented numerous talks at farmers days, study groups and formal training sessions for both producers and extension officers. Classes in both crop production and weed control have been presented at university level, and I have also presented a number of short courses, as well as lectures on a variety of topics, ranging from hydroponics to weeds.
