Dr. Meththika Vithanage is a Professor in the Department of Geochemistry at the Geological Survey of Denmark and Greenland, Denmark. Her work centers on quantifying concentrations and reaction kinetics of key and emerging pollutants, including microplastics, and Persistent, Mobile and Toxic contaminants. She advances understanding of their environmental fate and transport and develops remediation strategies using innovative geo-, bio-, and nanomaterials.Dr. Dimitrios A. Giannakoudakis obtained his PhD at the City University of New York, New York City, United States (February 2017). 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).Prof. Jagpreet Singh is Assistant Director at the Research & Incubation Center, Rayat Bahra University, India. His research focuses on the valorization of waste into advanced functional nanomaterials for environmental remediation applications, promoting sustainability, circular economy principles, and alignment with the UN Sustainable Development Goals (SDGs). He has published numerous articles on high impact journals, and was recognized among the World’s Top 2% Scientists by Stanford University and Elsevier for four consecutive years (2021–2024).
