I started in the science field as a research assistant while I was an undergraduate student at the University of Port Elizabeth (UPE) and later, after completing my MSc, I became an assistant technical officer at the Kings College Hospital in London. After returning to South Africa I joined the Malaria Research Unit of the Department of Pharmacology of the University of Cape Town as a laboratory technician at UCT, where I later I registered for a PhD.
Projects that I have been involved in included immobilization host enzymes involved in the HIV replication cycle on to polystyrene 96-well plates, isolation of biologically active compounds from medicinal plants. In vitro enzymatic assays were used in high throughput screening of test samples isolated from plants and animal tissues such as ELISA and chromatographic procedures to isolate compounds form plants and animal tissues such as TLC, affinity, column and ion exchange chromatography.
I developed laboratory skills such as standard biochemical techniques, operating analytical instruments such as HPLC, FPLC, fluorometer, SDS PAGE, pH meter, ELISA plate reader and spectrophotometry, sterile techniques from in vitro studies namely cell culture and DNA studies, microbiology techniques such as isolation and identification of bacteria and fungi.
My PhD project introduced me to in vivo efficacy and pharmacokinetic studies using a mouse model while evaluating new chemical entities for antimalarial activity.
