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. Rohan S. Dassanayake is a Professor of Biophysical Chemistry in the Department of Biosystems Technology at the University of Sri Jayewardenepura, Sri Lanka. His research focuses on the development and characterization of advanced biomaterials and their derivatives to address global challenges related to industrial dyes, carbon emissions, packaging, and biomedical applications. He specializes in intelligent bioplastics, particularly for food packaging, as well as nanocomposites for dye removal and carbon dioxide (CO2) capture. Additionally, his work includes the fabrication of biosensors for ocular pH detection, targeted drug delivery, wound dressing, and wearable electronic devices.Mika Sillanpää’s research work centers on chemical treatment in environmental engineering and environmental monitoring and analysis. The recent research focus has been on the resource recovery from waste streams.Sillanpää received his M.Sc. (Eng.) and D.Sc. (Eng.) degrees from the Aalto University where he also completed an MBA degree in 2013. Since 2000, he has been a full professor/adjunct professor at the University of Oulu, the University of Eastern Finland, the LUT University, the University of Eastern Finland and the University of Johannesburg.
