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. Dr. El Hadji Mamour Sakho received his PhD degree in Applied Physics from Mahatma Gandhi University, India in 2016. Currently he is a postdoctoral fellow in the Department of Applied Chemistry, University of Johannesburg, South Africa under the supervision of Prof. SO Oluwafemi His research focus is on the synthesis and characterization of graphene based hybrid materials for different applications such as solar cells, batteries, nonlinear optical applications, sensors, photocatalysts and polymer nanocomposites. Dr. Sundararajan Parani received his MSc degree in Industrial Chemistry from Alagappa University, India in 2006 and his PhD degree in Inorganic Chemistry from University of Madras, India in 2015. Currently he is a postdoctoral fellow in the Department of Applied Chemistry, University of Johannesburg, South Africa, under the supervision of Prof. SO Oluwafemi. His research interests focus on the development of nanomaterials and nanocomposites for theranostic application and water treatment. Mr. Thabang Calvin Lebepe received his B.Sc. in Biology and Chemistry at North West University, South Africa in 2014. He is currently pursuing his PhD's degree in the Department of Applied Chemistry; University of Johannesburg, South Africa under the supervision of Prof. SO Oluwafemi. His research interest is on the synthesis and characterizations of nanomaterials for different applications which include drug delivery and theranostics for HIV, cancer, and agricultural feed (using gold, Herbs and carbon-based nanoparticles).
