Featured scientist: Prof Ruan Veldtman
Prof Ruan Veldtman is an ecological entomologist whose research focuses on biodiversity, ecosystem services, invasive species, and the vital role insects play in healthy ecosystems.
His academic journey began at the University of Pretoria (TUKS), where he completed his PhD under the supervision of Professors Melodie McGeoch and Clarke Scholtz. This was followed by a postdoctoral research position at Stellenbosch University’s Centre for Invasion Biology (CIB) where he was one of the CIB’s first postdoctoral fellows.
Over the years he has built a notable career across research, national service, and academic leadership. He has also spent nearly two decades in service at the South African National Biodiversity Institute (SANBI) advancing biodiversity research and national environmental priorities. He also contributes to national and international collaborations on invasive species and pollination research.
In 2024 he became a NITheCS Associate and a year later was appointed Extraordinary Associate Professor at Stellenbosch University in 2025, bridging the gap between national research and academic training.
Peek in the Lab
Prof Veldtman’s research explores both the beauty and the threats within South Africa’s insect world. His work includes research on Vespula germanica, also known as the German wasp, investigating why South Africa hosts the slowest-known invasion and why this may be changing.
Another major initiative is the launch of the Bee Research Hub to support pollination research, beekeeping, and sustainable solutions for MSc and PhD projects.
His work matters because Prof Veldtman shows how invasive species and human activity disrupt ecosystems and how science can restore them. His researrch informs wasp management and strengthens agricultural and ecological resilience.
Current issues in the field
A major challenge in ecological research is the persistent shortage of funding. Prof Veldtman notes that South Africa can produce world class research but there is often a shortage of funding to scale and enhance the speed of research.
He emphasises the importance collaboration, stating that exchanging ideas across fields is not just beneficial it is essential for tackling complex environmental issues
His recommended reading is Pollinators, Predators & Parasites by C.H. Scholtz, Hennie de Klerk & Jenny Scholtz. This offers a clear, accessible introduction to the roles insects play in sustaining ecosystems.
Prof Veldtman shows that science thrives through collaboration, valuing every researcher and even the smallest creatures bees, beetles, wasps whose roles are vital in building a resilient future for South Africa’s ecosystems.
