He contributed significantly to research projects funded by the National Research Foundation (NRF) and the Korea Institute of Marine Science & Technology Promotion (KIMST) in South Korea. His primary research areas include polymer science, nanotechnology, and nanocomposites, composite materials, and surface modification. His recent work has explored hydrogels for applications in nutrient recovery, controlled drug delivery, water purification, and biomedicine. He has also delved into the development of photocatalysts with implications for nanotechnology, energy research, and environmental science. Prof. Pandey has authored more than 250 publications in peer-reviewed journals and international conferences. His scholarly contributions have garnered more than 9000 citations on Google Scholar in the past five years. Additionally, he is a guest editor for various scientific journals, including Materials Letters, Frontier in Chemistry, Biosensors, Chemosensors, Water, Materials, Molecules, and Polymers. He is an active member of scientific communities, including The Korean Society of Industrial and Engineering Chemistry, the Royal Society of Chemistry (RSC), the American Chemical Society, the Indian Science Congress Association (ISC), and the Materials Research Society of India (MRSI). He has received the Young Scientist award at the Indian Science Congress in India and has been recognised among the top 2% of scientists worldwide for year (2019, 2020, 2021, 2022 & 2023) in subject-wise analyses conducted by Stanford University. He has also authored more than 20 book chapters on advanced materials and technology for esteemed publishers in the USA. He has presented at numerous domestic and international conferences. Pandey has reviewed over 2000 articles while serving as a reviewer for over 300 internationally renowned scientific journals and research foundations.

Professor Peter Olubambi obtained BEng (Hons), MEng and PhD in Metallurgical and Materials Engineering. He is a Professor of Materials Engineering and is presently the Director of the Centre for Nanoengineering and Advanced Materials, as well as the Head of the School of Mining, Metallurgy and Chemical Engineering at the University of Johannesburg (UJ). His research activities focus on three key and interrelated fields of advanced materials processing; Powder Metallurgy, Nanomechanics and Tribocorrosion. His research efforts centered on the utilization of innovative powder metallurgical techniques for developing nanoengineered materials for automotive, aerospace, microelectronics, mines, energy storage, chemical and allied industries as well as for biomedical applications. He is a vibrant scholar and an NRF-rated researcher (C2). Through the various funding he has attracted, he has established a hi-tech powder metallurgy research laboratory at the Tshwane University of Technology, and the laboratories for Nanoengineering and Advanced Materials Research at UJ. He is an editorial board member of two international journals, a reviewer to many high impact factor journals, and has served as an organizing committee member to many local and international conferences. Over the past 10 years, he has graduated 36 master’s students, 22 doctoral students, and mentored six postdoctoral research fellows; 16 of these young, multicultural, and multinational persons currently hold academic positions as lecturers, senior lecturers, and associate professors within the South African HEI sector and outside South Africa. Prof Olubambi is currently supervising and co-supervising 21 doctoral students, 19 master’s students and mentoring 11 postdoctoral research fellows.
