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. Nandakumar Kalarikkal is an Associate Professor at the School of Pure and Applied Physics and Joint Director of the International and Inter University Centre for Nanoscience and Nanotechnology of Mahatma Gandhi University, Kottayam, Kerala, India. His research activities involve applications of nanostructured materials, laser plasma, and phase transitions. He is the recipient of research fellowships and associateships from prestigious government organizations such as the Department of Science and Technology and Council of Scientific and Industrial Research of the Government of India. He has active collaborations with national and international scientific institutions in India, South Africa, Slovenia, Canada, France, Germany, Malaysia, Australia, and the United States. He has more than 130 publications in peer-reviewed journals. He also co-edited nine books of scientific interest and co-authored many book chapters. 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.
