Prof. Vincenzo Naddeo (納文 森 - Chinese name for the appointments in Taiwan) is Director of the Sanitary Environmental Engineering Division (SEED) at the Department of Civil Engineering of the University of Salerno (Italy), where he drives research and academic activities in the Environmental Engineering fields. He serves as an affiliate professor at both the Department of Civil and Environmental Engineering of the University of Washington (Seattle, WA, USA) and at the Department of Water Resources and Environmental Engineering of the Tamkang University (New Taipei City, Taiwan). Prof. Naddeo serves the Italian Ministry of the Environment as a member of the National Committee on IPPC (Integrated Pollution Prevention and Control). Since 2018 prof. Naddeo is CEO and co-founder of Sponge s.r.l., a Spin-Off of the University of Salerno working on Environmental Technology. His research focuses on advanced water/wastewater treatment, characterization and control of environmental odours and environmental impact assessment (EIA). He developed advanced biological processes for wastewater treatment and control of emerging contaminants, novel ultrasound-based technological processes for treating environmental matrices (solid, liquid and gaseous) and biotechnologies for wastewater re-use with simultaneous energy production within the framework of the circular economy. Prof. Naddeo is the coordinator of several European/international and national research projects, supervisor of PhD and master students, and member of the scientific board in several national and international conferences where he was often invited as a plenary or keynote speaker. Prof. Naddeo was the general chair of two international conference series, WaterEnergyNEXUS (since 2017) and UrbanWaterSECURITY (since 2019). Prof. Naddeo is also actively involved in various scientific organizations, funding agencies, and European networks. He holds seven patents, 4 on innovative technologies for the advanced treatmentof water or wastewater, 2 on the next generation of electronic nose (e.Nose) and 1 patent on an innovative photo-bioreactor for the sequestration of CO2. prof. Naddeo serves the editorial board of several ISI journals, and he is (co-)author of over 200 refereed publications in ISI journals, congress proceedings and book volumes.Dr. Choo received his Ph.D. degree from Seoul National University, Korea in 1996 and since then has been working on membrane technology for water and wastewater treatment, pursuing breakthrough innovations for the development of novel membranes and membrane processes. His recent research interests include electrochemical membrane filtration, quorum quenching membrane bioreactors, and iron oxide coated media filtration. He is keen to find synergistic strategies for the best practices of separation, treatment, abatement, and recovery in the management of water and wastewater streams. He has been involved in academic societies, such as Korean Society of Environmental Engineers, Korean Society on Water Environment, Membrane Society of Korea, International Water Association, American Chemical Society, and World Filtration Congress as an active member. Mohamed Ksibi, completed his Ph.D. in 1993 in Applied Chemistry at the University of Poitiers, France. He also gained the Habilitation (HDR) in Chemistry from the University of Sfax, Tunisia in 2003. He was appointed as a full Professor of Chemistry in 2009 at the Higher Institute of Biotechnology of Sfax (ISBS). His areas of research interest include removal and toxicology assessment of persistent organic pollutants in the environment (water and sediment/soil). He has supervised 11 thesis to completion and examined a further 4 PhDs. He has also supervised 15 MSc. thesis. He has co-published about 90 papers, 8 book chapters and co-edited 2 books: Recent Advances in Environmental Science from the Euro-Mediterranean and Surrounding Regions (1st Edition 2017, 2 volumes) (2nd Edition 2019, 3 volumes). He is the co-Editor-in-Chief of the Euro-Mediterranean Journal of Environmental Integration (h-index 25).Dr. Ksibi had been the Institute’s Deputy Director of the ISBS from August 2011 until December 2017, he served as the Director of the Department of Biotechnology and Health at ISBS from May 2008 until May 2011. He has also been the chairman for the 1st in 2017, the 2nd in 2019 and the 3rd in 2021 of the  Euro-Mediterranean Conference for Environmental Integration.
