Professor Rooyen T Mavenyengwa joined the University of Zimbabwe, Department of Medical Microbiology in January 2002 as a Lecturer from The Biomedical Research and Training Institute (BRTI) where he had worked as a research assistant. He holds a BSc (Hons) in Biological Sciences, MSc in Medical Microbiology, both from the University of Zimbabwe in addition to a Post Graduate Certificate in Education from the same institution. He graduated with a DPhil from the Norwegian University of Science and Technology in Trondheim, Norway in 2012. Professor Mavenyengwa was promoted to Senior Lecturer Grade on 1 January 2013. He is the first African scholar to use molecular techniques to characterize Group B streptococcus (GBS) which causes infections mainly in pregnant mothers and children with a view to identifying suitable and potential vaccine candidates relevant for the local population. His pioneering work on GBS was done in collaboration with international partners from Norway, South Africa and Namibia. He has published numerous research articles in peer-reviewed high impact journals and has presented his scientific research work at local, regional and international conferences and symposia across the globe. His main research highlight is the discovery of the new surface-anchored protein in GBS called the “Z” protein. He has since published a book on molecular characterization of Group B Streptococcus. His other research interests include antibiotic resistance testing, HIV and AIDS, and other viruses of public health importance, Transfusion Transmissible infections (TTIs), Cryptococccus and Tuberculosis. Professor Mavenyengwa has received other numerous academic, research and travel awards in recognition of his outstanding contribution to Medical Microbiology scientific research. His main area of specialization is Medical Bacteriology focusing on Streptococcology and Molecular Biology which he passionately teaches to both undergraduate and postgraduate medical students. He coordinates and facilitates the training of the HIV Rapid testing course in partnership with the Medical Laboratory and Clinical Scientists Council (MLCSC). He also leads a vibrant team at the WHO-funded Zimbabwe National Virology Laboratory which is mandated by the Ministry of Health and Child Care to carry out routine diagnostic and surveillance on Polio, Rubella, Measles and Rota viruses for Zimbabwe and Malawi. He was appointed Chairman of the Department of Medical Microbiology on 1 October 2016, the appointment which he holds to date.
