Prof. Jephias Gwamuri

Professor/Senior Lecturer - Applied Physics

 I hold a B.Sc. in Physics & Electronics from Cuba, a Masters in Lasers and Applied Optics from NUST and a PhD in Material Sciences and Engineering from Michigan Technological University, USA. I am a specialist in Materials Science and Engineering, and have coordinated a number of projects including the International Atomic Energy Agency (IAEA) funded RAF-8040 Zimbabwe project and the Regional Environmental Initiative Network (REIN) –-- Africa funded Biofuels Project. I have co-authored several research articles, technical reports, a policy brief and a contribution to a book chapter. For some of my research endeavours, I have received a handful of awards including the ICTP-African LAM network award, the Most Outstanding Scholar Award (Michigan Tech) and the researcher of the year awards at NUST. I have led and collaborated in various solar PV and 3D printing projects including; Open –-- Source 3D printers for development, solar PV Microgrids, 3D Printers for education, PV systems optimisation, Energy Storage, Electric Vehicles, Artificial Intelligence, and IOT driven system, among others. I have vast experience in grants and project proposals writing and management, Technology Transfer, Intellectual Property Management and Commercialisation. I am former Director of Research and Innovation at Great Zimbabwe University. Among other attributes, I am an active reviewer (Journals and Conferences Proceedings) as well as program accreditations. I supervised students’ research projects (B.Sc., M.Sc., M.Phil., and Ph.D.) and examined students’ thesis (B.Sc., M.Sc., M.Phil., and Ph.D.) mostly as an external examiner. I am a member of --- the International Network on Appropriate Technology (INAT), Society of Photonics Instrumentation Engineers (SPIE), The Minerals, Metals & Materials Society (TMS), Optical Society of America (OSA), among others.
