Professor Dipti Ranjan Sahu is a Professor of Physics in the Department of Biology, Chemistry and Physics in the School of Natural and Applied Sciences at the Namibia University of Science and Technology (NUST) Windhoek, Namibia. He received his doctoral degree in Physics from Utkal University, India. He has worked as a research fellow, postdoctoral researcher, visiting scientist and faculty member at institutions such as the Institute of Materials Science (India), National Taiwan University, National Cheng Kung University (Taiwan) and University of Witwatersrand (South Africa). His research focus is on multifunctional materials including nanomaterials, ceramic, composites, spintronics, magnetic materials and application of functional materials in devices. Prof Sahu is a fellow of the International Association of Advanced Materials (IAAW) in recognition of exceptional contribution to the field of science, engineering and technology, particularly in the realm of materials for multi-inter-transdisciplinary applications.

Professor Sahu is dedicated to his research in Multifunctional Materials and Nanotechnology.  Over the years, his research activities have contributed to the understanding of concepts such as high-density memory devices, multiferroics material, new generation dilute magnetic semiconductors, electrochromic cells, nanowire and nanoparticle solar cells and intelligent glass curtains for advancing multifunctional thin film materials in the next generation nanoscale electronic devices. His significant novel research findings gained national and international recognition in the field of multifunctional materials and devices. His pioneering research on transparent conducting oxides has provided a new dimension to the energy field. On the other hand, his collaborative research work on process flow for fabricating magnetic perovskites on silicon stimulated research interest for many companies including Intel for application in high-density memory.

He has strong research collaborations with researchers in the USA, Germany, South Africa, Taiwan and India. He has published 90 international peer-reviewed journal articles, six (6) book chapters, 6 books and more than 100 research articles in conference proceedings and meetings. His research publications received more than 2650 citations and Prof Sahu currently has a Scopus H-index factor of 27. He is cited as number 1(one) researcher in Namibia University of Science and Technology according to AD world scientific index. He also serves as a reviewer for more than 35 international journals and has reviewed more than 300 articles. Professor Sahu was awarded as C1 rated researcher (2011-2016) by the National Research Foundation (NRF) of South Africa as well as being a grant holder of three (3) NRF funded projects. He is also on the editorial board member of a few journals and books such as Imaging and Radiation Research, Fuels & Energy Science Journal, African Review Journal and Intech publisher. He has served as examiner of Masters’ and PhD theses for several universities in different countries. Professor Sahu is the recipient of many international awards such as Australian Research Council Fellowship, Spanish Government Excellence Research Fellowship, National Science Council Taiwan Fellowship and Council for Science and Industrial Research Fellowship in India.  He has also organised international conferences and served as conference and session chairperson. Currently within the Faculty, Professor Sahu is the research co-ordinator and the principal researcher within the Nanotechnology and Material Science niche area.

Current research contribution is related to the use of experimental processing and characterization techniques for application of electrochromic film for smart window application, nanostructured coatings for energy conversion and storage, development of electrode for green hydrogen production and materials for green hydrogen storage.
