Dr. Maulin P. Shah is Chief Scientist and Head of the Industrial Waste Water Research Lab, Division of Applied and Environmental Microbiology Lab at Enviro Technology Ltd., Ankleshwar, Gujarat, India. His work focuses on the impact of industrial pollution on the microbial diversity of wastewater following cultivation-dependent and cultivation-independent analysis. His major work involves isolation, screening, identification, and genetically engineering high-impact microbes for the degradation of hazardous materials. His research interests include biological wastewater treatment, environmental microbiology, biodegradation, bioremediation, and phytoremediation of environmental pollutants from industrial wastewaters. Susana Rodríguez-Couto (female) got her B.Sc. and M.Sc. in Chemistry (Industrial Chemistry) from the University of Santiago de Compostela in 1992 and her Ph.D. in Chemistry in 1999 from the University of Vigo, obtaining the maximal grade (magna cum laude) and, in addition, she was awarded with the Extraordinary Prize for Doctoral Thesis in Chemistry. She worked as an Associate Professor and an Isidro Parga Pondal Senior Researcher at the University of Vigo (2000-2004), as a Ramón y Cajal Senior Researcher at Rovira i Virgili University (2004-2008) and as an Ikerbasque Research Professor (2009-2019). She has also worked as an Invited Researcher at the Institute from Environmental Biotechnology, Graz University of Technology (Austria) and at the Department of Biological Engineering, University of Minho (Portugal). In 2008, she received the I3 Professor from the Spanish Ministry of Science and Education to the recognition of an outstanding research activity. In March 2021 she is joining LUT School of Engineering Science at Mikkeli, Finland, as a Full Professor in biological water treatment. She has published more than 140 articles in highly reputed international journals (h index 42). She is editor of several journals (3Biotech, Frontiers) and 14 Elsevier books. Celia Bertha Vargas de la Cruz. She is Assistant Professor of Biotechnology and microbiology at San Marcos University Lima-Perú. Her experience in biotechnology, applying omics has allowed to use living organisms for the removal of toxic pollutants form liquid and hazardous waste. She is handling various projects on waste water treatment, biofiltration, environmental sustainability. Prof. (Dr.) Jayanta Kumar Biswas is a Professor at Department of Ecological Studies and International Centre for Ecological Engineering, University of Kalyani, West Bengal, India. He obtained M.Sc. in Zoology, M.Phil. in Ecology and Ph.D. for his work on Eco technological management of aquatic systems. His spectrum of research interest and expertise span the following focal areas: ecotoxicology and bioremediation of toxic metal(loid)s; ecological engineering and eco technological remediation of water and soil contaminants; environmental microbiology; Nano biotechnology; dynamics of nutrients and toxic contaminants in water and soil; bio regenerative reclamation of wastewater.
