Mr. Adam Shnier is a part-time PhD student at the University of the Witwatersrand, South Africa where he also completed an Honours degree (with distinction) in Chemistry and a BSc in Chemistry and Material Science. His research focuses on hybrid-perovskites for photovoltaic applications. This work involves thin-film fabrication and the use of advanced X-ray diffraction techniques to characterise thin films as well as bulk materials. He is also interested in developing viable cost-effective alternatives to commercial equipment for emerging regions. He received the South African Chemical Institute Post-Graduate Award in 2020 for his versatile approach to his research work.

Dr. Francis Otieno is currently a full-time lecturer at the department of Physics and Materials science, Maseno University, Kenya. He holds an Msc and PhD in Physics and recently completed a 3-year postdoctoral fellowship at the University of the Witwatersrand, South Africa funded by the Synchrotron Techniques for Africa Research and Technology-Global Challenge Research Fund (START-GCRF). He is a recipient of several funding including the British Council - South Africa, under the Newton Fund in partnership with the Department of Higher Education and Training (DHET) South Africa and recently the ARUA/Carnegie Early Career Research Fellowship. His research interest includes fabrication and characterization of thin films solar cell devices including organic solar cells, dye sensitized solar cell and perovskites with a view to enhance performance using plasmonics, spectral conversion, varied device structure and probing into the morphology using Synchrotron Soft X-Rays. His focus is on thin film growth and characterization via physical deposition techniques such as sputtering, thermal evaporation, pulse laser deposition etc.

David Billing is currently a professor at the School of Chemistry, at the University of the Witwatersrand. His research currently focusses on structure-property relationships in solid eletrolyte materials typically for energy applications, using advanced X-ray and Neutron diffraction and total scattering techniques. Of particular interest is the use of in situ and in operando studies, as well as the use of synchrotron based techniques to gain a better understanding of the real structure and performance of the materials under investigation.
