Angeline Jacoby obtained her B.Sc. degree (Genetics and Botany -1988) and B.Sc. Hons (Genetics - 1989) at the University of the Free State. She became involved in breeding programmes for Gladiolus and Ornithogalum species while working as assistant agricultural researcher at the ARC-Roodeplaat Vegetable and Ornamental Plant Institute, Pretoria till September 1990. After spending nearly six years at a nursery in East London and one year at Port Rex High School she commenced with her postgraduate studies at the University of the Free State in April 1997. Her M.Sc. (Botany) with the title “Micropropagation of Pinus species” was obtained in 1999, under the supervision of Proff. A.J. van der Westhuizen and A.-M. Botha-Oberholster and in 2003 she completed her Ph.D. study under the supervision of Prof. M.T. Labuschagne with a thesis entitled “Genetic variability in the Solanum nigrum L. complex and related species in South Africa”. She is a member of the Southern African Plant Breeders Association. During 2005 to 2007 she was a Post-Doctoral Fellow at the Central University of Technology, Free State, in the Unit for Applied Food Safety and Biotechnology. She has authored and co-authored papers in accredited journals and several posters at conferences. She was appointed as senior lecturer in the Department of Plant Sciences, Plant Breeding division in 2013 where she teaches undergraduate courses and supervises postgraduate students.
