Prof.Dr Dimetry visited the ARC in Pretoria, South Africa South Africa, and I visited her in Cairo. I was requested to evaluate a Ph.D. thesis from Prof Dimetry’s Laboratory.
  • Manager of the Programme Pesticide Science of ARC-PPRI (2000 to 2012), with research on the effect on the environment of insecticides used for malaria control; the analysis of pesticide residues; the control of rodents and insect pests to minimize losses of stored grain in rural areas; and the environmental management of pesticides.
  • Over the last 12 years, I was Manager of the Programme Pesticide Science, of the Plant Protection Research Institute, of the Agricultural Research Council, in Pretoria.
  • I was appointed as principal investigator of the Memorandum of Agreement (Co-operative research on Botanical Pesticides) between ARC-PPRI and Prof.Dr. Nadia Dimetry of the National Research Centre, Cairo, Arab Republic of Egypt (1997 – 1999).
