Completed a BSc Hons in Entomology at Rhodes University, South Africa in 1994; joined the research staff of the Weeds Division, Plant Protection Research Institute in South Africa, investigating the biocontrol options using natural enemies on several target species including Lantana camara. Completed a PhD at Rhodes University with Prof. Pat Hulley and Prof. Martin Hill in 2003 while working at PPRI till 2000. I took my first postdoctoral fellowship in 2002 with Dr Mary Kelly-Quinn at UCD. I joined the staff in June 2008 as a lecturer in Biological Control and integrated pest management. |
