Research Interests 

My research interests are in anemia in pregnancy. The current research compares two groups of pregnant mothers, HIV positive and HIV negative groups. The main objective is to study prevalence and associated risk factors in these two groups. The impact of these risk factors on pregnancy outcomes is also being studied.

Research Activities

Research activities are in tandem with the Department research theme, aiming to understand the impact foetal HIV stimulation and in utero cumulative HAART exposure early in life through into breastfeeding on pregnancy outcome, infant health, growth, immunity, and neuro-development taking into account a range of factors, including co-infection with persistent viruses, maternal nutritional status and breastfeeding, together with maternal HIV status, levels of immune suppression and immune dysregulation, gut microbiome and HAART use duration in the HIV+ women. Numerous maternal factors being investigated call for a multi-disciplinary collaborative research with the aim to improve the care of mothers and their babies at the same time creating a vibrant and sustainable research culture in the Department and UZ-CHS with the mandate to contribute towards evidence based medical practice and sound policy formulation. In the long term contributing to strengthening of critical HIV and co-infections cutting edge laboratory and clinical research at the UZ through technology transfer via international collaboration.

Research

The research theme is "Immunology of the immuno-compromised host". My research activities include studying biomarkers associated with mother-to-child transmission (MTCT) of HIV, prevention, diagnosis, and treatment of MTCT of HIV; development and evaluation of novel point-of-care diagnostics tools for HIV and TB, immunogenetics of HIV and TB as well as investigations of immunological and virological biomarkers of HIV disease progression amongst ART-naive patients. I also train Masters/DPhil students and other younger researchers in conducting clinical trials in HIV/AIDS, TB and other HIV/AIDS related co-infections.

Current research

Optimization of Option B+ for PMTCT of HIV through implementation of point-of-care maternal HIV load, early infant diagnosis (POOCBART Study). The main objective of this project is to implement effective point-of-care through early infant diagnosis of HIV, maternal and infant VL monitoring to optimize prevention of mother to child transmission of HIV, maternal and infant treatment.
