Fields of academic interests

Teaching Interests:

  • Agricultural Meteorology and Ecozones (SSW101-D)
  • Environmental Management for Civil Engineering (EGE401-T, EGE 401-P)
  • Environmental Management for Chemical Engineering (EMC401-T, EMC 401- P)
  • Impact management and mitigation

Research Interests:

My interest lies in waste minimization efforts and initiatives through various projects of recycling of domestic waste: institutional, community, commercial and municipal. One such an opportunity which exists in every residential garden as well as in municipalities is to recycle garden waste into an useful product compost. The environmental impact needs to be investigated to ensure that the composting does not have a detrimental effect on the immediate environment. My interest is to determine the impacts and to suggest workable mitigation measures to promote composting on a large scale in South Africa as part of the solution to the growing waste problem.
