Patrick Omoregie Isibor, Ph.D., is a specialist in Pollution Studies and Ecotoxicology and a Lecturer/ Researcher in the Department of Biological Sciences at Covenant University. He received his Ph.D. and M.Sc. in Environmental Quality Management from the University of Benin and a B.Sc. in Zoology from Ambrose Alli University. Dr. Isibor’s research interests include ecotoxicology, hydrobiology, bioaccumulation, biosequestration, biodiversity conservation, and aquatic ecology. He is a member of the Association for Environmental Impact Assessment of Nigeria (AEIAN), the International Association of Risk and Compliance Professionals (IARCP), and the African Society for Toxicological Sciences (ASTS). Dr. Isibor is co-editor of the book Biotechnological Approaches to Sustainable Development Goals (Springer, 2023), an Editor for the African Journal of Health, Safety, and Environment, and a reviewer for several reputable international journals.   Geetha Devi, Ph.D., is an Associate Professor in Chemical Engineering in the Department of Mechanical and Industrial Engineering, College of Engineering at National University of Science & Technology, Oman. She received her Ph.D. in Nanotechnology from the National Institute of Technology, India. She has more than 80 International peer-reviewed journal and conference publications and 12 funded research projects from various funding agencies, including the Industry Innovation Center (IIC), The Research Council (TRC), Oman, and National University Student and Faculty Research Grants (NUSRG/ NUFRG) in the key research areas of nanotechnology, wastewater treatment, biopharmaceutics, and drug delivery. Dr. Devi has worked on numerous research collaborations with institutions such as the University of South Carolina, USA, Jamia Milia Islamia University, India, the National Institute of Technology (NIT), Durgapur, Khalifa University, Abu Dhabi, Sultan Qaboos University (SQU), Oman, University of Nizwa (UoN), and the Middle East Desalination Research Center (MEDRC), Oman, in the emerging areas of nanotechnology, corrosion control, waste management, and water treatment. She is a Scientific Committee Member for selecting the Omani Young Water Researchers Award for the undergraduate and postgraduate category with the MEDRC. She is an MSc thesis external examiner for Sultan Qaboos University. Dr. Devi received the Best Researcher Award from the National University of Science & Technology for 2021-22. She serves as an editor/editorial board member for several journals and an external reviewer for The Research Council (TRC), Oman.  Alex Ajeh Enuneku, Ph.D., is a specialist in Pollution Studies and Ecotoxicology and Head of the Department of Environmental Management and Toxicology, Faculty of Life Sciences, at the University of Benin.
