Dr. Balasubramani Ravindran is an Assistant Professor in the Department of Environmental Energy and Engineering, at Kyonggi University, Suwon-Si, South Korea. His research focuses on solid waste treatment and wastewater generated from domestic and industrial sources through aerobic and anaerobic fermentation, composting and vermicomposting, activated carbon, biochar or black carbon amendments, nanotechnology applications, and phytotoxic/plant growth studies. Dr. Ravindran has over 150 publications in international peer-reviewed journals, filed patents, edited books, and published book chapters. He has received national and international research grant funds for his research projects. He serves as an academic editor, editorial board member, or guest editor on several international journals.Dr. Sartaj Ahmad Bhat is working as a JSPS Postdoctoral Researcher at the River Basin Research Center, Gifu University, Japan. He received his Ph.D. in Environmental Sciences from Guru Nanak Dev University, India, in 2017. His primary research focuses on the development and evaluation of treatment technologies for organic waste and wastewater from domestic and industrial outlets as well as organic waste recycling, with a focus on the biological and sustainable treatment by earthworms. He has published over 60 papers in peer-reviewed journals and co-edited 13 books. Dr. Bhat serves as an associate/academic editor, editorial board member, or advisory board member on more than 15 journals. He has been awarded several postdoctoral/research fellowships, and has also received the 2020 Outstanding Reviewer Award from the International Journal of Environmental Research and Public Health and Top Peer Reviewer 2019 award for Environment and Ecology (Web of Science).Prof. Gareth Griffiths is an internationally recognized research biochemist specializing in lipid biochemistry, currently based at the European Bioenergy Research Institute at Aston University, Birmingham, United Kingdom. Renowned for his pioneering work on triacylglycerol and polyunsaturated fatty acid synthesis, his research is now focused on developing microalgae for high value products and biofuels, and, in particular, green microalgae and their extracted protein and lipid components. Prof. Griffiths has published over 60 research articles, and his work has gained more than 3,000 citations.
