Professor Oluwafemi is a fully-fledged academic that is involved in Teaching & Learning, Research, Community Engagement, staff and student mentorship among many other activities. His research interest is in the synthesis of binary, ternary and quaternary semiconductor nanomaterial and nanostructures such as quantum dots, metal nanomaterials, core-shells, doped nanostructures and polymer nanocomposites for different applications which includes biological, (basically for cancer treatment ie imaging, labelling, drug delivery photodynamic therapy and photothermal therapy), optical (development of optical devices), environmental (sensing and determination of environmental pollutants), nanotoxicology and water treatment. He is also involved in the indigenous knowledge system (IKS) for value added chain using different South African medicinal plants. This involves isolation, extraction, biological activity testing, and synthesis of nanomaterial using the plant extract and packaging for pharmaceutical purposes.
