Director's Profile

Professor Pascal Obong Bessong did his graduate training in South Africa, Nigeria, France and the United States. A former head of the Department of Microbiology at the University of Venda (2007-2012), he established the HIV/AIDS & Global Health Research Programme in 2012, with capabilities for molecular, cell biology, and community-based research, and postgraduate training. His research focuses on microbiological investigations impacting on translational science and global health. Specifically, he is interested in host and viral determinants of HIV drug resistance and the sustainability of highly active antiretroviral therapy (HAART); the impact of HAART on the pathogenesis of malignancy associated viruses; and the interaction of enteric viruses, vaccine response, gut integrity, growth and development in young children, particularly in populations of low socio-economic status. He is the principal investigator of Transmitted and acquired HIV drug resistance in Limpopo, Bioprospecting platform, and MAL-ED South Africa research projects. Professor Bessong is the director of the national annual training workshop on gene expression and biotechnology, and the South Africa director of a Global Infectious Diseases Research Training Program, and the WHIL Innovations Postdoctoral Fellowship Program.

He is a technical adviser to the International Science Foundation; and frequently reviews research grant proposals for the Infectious Diseases Control Programme of the Government of Hong Kong; Medical Research Council, National Health Laboratory Services, National Research Foundation of South Africa; and on adhoc basis for UK Medical Research Council and Canadian Institutes for Health Research. He has successfully trained 36 MSc/PhD students, and authored/co-authored more than 115 peer reviewed scientific publications. He is on the editorial advisory board of several scientific journals, and reviews doctoral theses on virology for several universities.

Professor Bessong’s research and human capacity development initiatives are supported by the South Africa Medical Research Council, Department of Science and Technology, Technology Innovation Agency, National Research Foundation; Fogarty International Center/NIH (USA), and the Bill and Melinda Gates Foundation through the FNIH/University of Virginia, USA.

The course has three components: lectures, problem solving and small group discussions, and laboratory based practical sessions. Topics covered include:

  • Genes, Gene Expression and Genomics
  • RNA Polymerases and their Roles in Gene Expression
  • The Genetic Code and Protein Synthesis
  • Mechanism and Control of Translation
  • mRNA Transcription and Processing
  • Post-transcriptional Regulation of Gene Expression
  • Non Coding RNAs and RNA Editing

In the course of her postgraduate training she had research fellowships at the Myles H. Thaler Center for AIDS and Human Retrovirus Research, University of Virginia, USA and at J. Craig Venter Institute, Maryland USA. She has been the recipient of the Pfizer International Fellowship Initiative; bursary and mobility grant from the National Research Foundation, and the South African AIDS Vaccine Initiative. In 2010, she was awarded the DST/TATA South African Women in Science Award, in the Young Scientist category. In 2015, she received training in grant management from the National Institutes of Health, USA.

Dr. Mavhandu-Ramarumo’s research interest is on molecular genetics with a focus on the molecular basis of HIV drug resistance and its implications on the efficacy and sustainability of first line antiretroviral therapy. She is also interested in the preclinical evaluation of compounds for anti HIV properties. She has co-authored several peer reviewed articles in reputable journals such AIDS Research and Human Retroviruses, Archives of Virology, and South African Medical Journal. She is an awardee of the Thuthuka-NRF programme to investigate biomarkers of adherence to antiretrovirals, and to the phenotypic significance of observed but uncharacterized mutations that arise in HIV-1 subtype C upon drug exposure. She is the co-principal investigator of an MRC funded project on drug resistance in Limpopo Province.
