Kui Huang is a professor and department chairman of specializing in the subject of environmental ecological engineering at the School of Environmental and Municipal Engineering, Lanzhou Jiaotong University, China. He received his PhD in Civil and Environmental Engineering from Gifu University, Japan in 2014. He served as a researcher for the River Basin Research Center at Gifu University for two years before joining Lanzhou Jiaotong University in 2015. His teaches courses including water engineering construction and environmental ecological engineering. His research interest involves fundamental and applied aspects of biological contaminant reduction, aerobic biodegradation process, water quality safety in river basin, and organic solids recycling, with a focus on biological and sustainable treated system of wastes by earthworms. Dr. Sartaj Ahmad Bhat is working as a JSPS Postdoctoral Researcher at the River Basin Research Center, Gifu University, Japan. He received his Ph.D. in Environmental Sciences from Guru Nanak Dev University, India, in 2017. His primary research focuses on the development and evaluation of treatment technologies for organic waste and wastewater from domestic and industrial outlets as well as organic waste recycling, with a focus on the biological and sustainable treatment by earthworms. He has published over 60 papers in peer-reviewed journals and co-edited 13 books. Dr. Bhat serves as an associate/academic editor, editorial board member, or advisory board member on more than 15 journals. He has been awarded several postdoctoral/research fellowships, and has also received the 2020 Outstanding Reviewer Award from the International Journal of Environmental Research and Public Health and Top Peer Reviewer 2019 award for Environment and Ecology (Web of Science).Prof. Fusheng Li is a Professor in the Division of Water System Safety and Security Studies and the Graduate School of Engineering at Gifu University, Japan.
