Prof Cronjé completed her BSc in Biological Sciences (majors Biochemistry and Zoology) at the Rand Afrikaans University, her BSc Hons degrees in both majors and MSc at the Free State University and completed her PhD in Biochemistry at the Rand Afrikaans University. The latter institution was incorporated in the newly established University of Johannesburg in 2005. Prof Cronjé is currently the Head of Department of Biochemistry at UJ, and has functioned in this role since 2011.
The overarching theme of her research focusses on programmed cell death, in particular the induction of apoptosis in cancer, and bifurcates with photo dynamic therapy (PDT) and novel anti-cancer compounds forming core groups of research, the latter resulting in the filing of various patent applications that are being prosecuted in Australia, Canada, Europe, India, the US and SA. She has served as a member (current Secretariat) of the Board of Directors of the International Cell Death Society since 2009 and is the current President of the South African Cell Death Society, a satellite chapter of the ICDS. She is currently also an editorial board member of the journal Cell Communication and Signaling, a Nature Springer journal. She continues to supervise MSc and PhD postgraduates in Biochemistry, and currently two post docs are hosted in her group; their research activities have led to a number of publications in peer-reviewed journals and national and international conference contributions.
