Nowadays, he serves as an assistant professor at the University Marie Curie Sklodowska (UMCS), Lublin, Poland. His research is focused on the development of composite porous nanomaterials for (photo)(sono)(piezo)catalytic technologies for biomass valorization and (micro)plastics upcycling to green chemicals, as well as for air and water purification, linking physicochemical properties to performance and involved mechanisms. He coauthored more than 140 articles, 1 monograph, 7 edited books, and 17 book chapters with over 7000 citations. Since 2021, he has been included in the Top 2% Most Influential Scientists worldwide (Stanford list, Elsevier).Dr. Ioannis Anastopoulos is an associate professor at the Department of Agriculture, University of Ioannina, Arta, Greece. He has conducted postdoctoral research at the Agricultural Research Institute (Cyprus), the University of Patras (Greece), the University of Cyprus (Cyprus), and the Hellenic Mediterranean University (Greece). His research focuses on the estimation of greenhouse gas emissions from agricultural soils following the application of organic and inorganic materials, the development of adsorbent materials for wastewater treatment, and the use of organic amendments for soil remediation. He has authored more than 130 articles in peer-reviewed journals with over 12,000 citations and has been included among the Top 2% Scientists worldwide for the years 2019–24 (Stanford list, Elsevier).
