Assistant technical officer at the Institute for Plant Biotechnology (IPB). I completed my MSc in Plant Biotechnology at the IPB at Stellenbosch University in 2023 under the supervision of Dr Christell van der Vyver. My research focused on improving drought tolerance in sugarcane plants through the genetic modification of genes involved in photosynthesis.
