Mika Sillanpää’s research work centers on chemical treatment in environmental engineering and environmental monitoring and analysis. He received his M.Sc. (Eng.) and D.Sc. (Eng.) degrees from Aalto University, where he also completed an MBA degree in 2013. He has published more than 850 articles in peer-reviewed international journals. Dr. Sillanpää has received numerous awards for research and innovation. He is the first Laureate of Scientific Committee on the Problems of the Environment (SCOPE)’s Young Investigator Award, which was delivered at the UNESCO Conference in Shanghai 2010 for his “significant contributions, outstanding achievements, and research leadership in Environmental Technological Innovations to address present water pollution problems worldwide, especially with regard to wastewater treatment and reuse. He has supervised over 60 PhDs and has reviewed over 250 academic journals and published more than 1000 articles in peer-reviewed international journals. He has served on the editorial boards of several scholarly publications. Dr. Marina Shestakova received a master’s degree in Environmental Engineering from the High School of Technology and Energy, Russia. After that, Dr. Shestakova continued her studies in Finland and received an MSc (Technol.) in Bioenergy Technology in 2010. In 2012, she began her PhD studies under the supervision of Prof. Sillanpää at the Lappeenranta University of Technology. She received her DSc degree in Green Chemical Technology in 2016. Dr. Shestakova has also conducted research work at the University of Alicante (Spain) and Coventry University (UK). Currently Dr. Shestakova works as a postdoctoral researcher in the Laboratory of Green Chemistry, Lappeenranta University of Technology. Her areas of interest include water treatment, environmental engineering, environmental remediation, renewable energy, nanocomposites, and nanomaterials
