Asfa Rizvi works at Department of Department of Botany, School of Chemical and Life Sciences, in Jamia Hamdard University, India. She has extensive experience in the areas of biotic and abiotic stress, environmental microbiology (heavy metals-PGPR-crop interactions), biofertilizers technology, bioremediation technology (microbiome-based remediation strategies), and soil pollution (inorganic pollutants). Dr. Rizvi has published over 50 high impact factor scientific papers, review articles, and book chapters in national and international peer reviewed journals. Mohammad Saghir Khan is a professor of microbiology at the Department of Agricultural Microbiology in Aligarh Muslim University, India. He has 27 years of teaching experience at the postgraduate and doctoral levels, as well as 29 years of research experience in environmental microbiology, nanotechnology, biofertilizer technology, soil pollution, bioremediation technology, immunology, soil microbiology and food crop production. Dr. Khan has published over 300 scientific papers including, original research papers, review articles, and book chapters in various national and international publications with over 22,000 Research citations, and edited 11 books, seven of which have been published under Springer. Currently, he serves as an associate editor for three international journals, namely the International Journal of Environmental Science & Technology, Frontiers in Environmental Science: Toxicology, Pollution, and the Environment and Journal of Modern Agriculture and Biotechnology. Eloisa Pajuelo is a professor of microbiology at the University of Seville, in Spain. She has 25 years of experience studying plant-microbe interactions, particularly the interaction of legumes with rhizobia, microbiota of halophytes under stress by heavy metals, and stresses caused by factors involved in climate change (namely salinity, drought, and low/high temperature). Her current research focuses on the design and application of biofertilizers in the current situation of multiple stresses that constraint plant growth. Dr. Pajuelo’s expertise also includes soil bacteria dynamics, endophytes, PGPR, and phytoremediation. She has published over 125 papers and book chapters in highly recognized peer reviewed international journals. Khalid Oufdou is a full professor at the Cadi Ayyad University, Faculty of Sciences Semlalia, in Morocco. He developed more than 20 research projects in Spain, France, Germany, Tunisia, Portugal, Sweden (3 IFS grants), and the European Union. He was awarded fellowships by the Deutscher Akademischer Austauschdienst and Alexander von Humboldt foundation in Germany. Professor Oufdou has extensive experience in areas related with plant-microbe interactions, stress management of contaminated environments, plant biotechnology, microbial ecology, and antibacterials. He has published more than 80 research papers with high impact factors. Bilal Ahmed is a Research Scientist at Purdue University, USA. His research areas include microbiology, nanotoxicology, nano-bioremediation, and molecular microbiology. Dr. Ahmed has published over 60 research publications in peer reviewed high impact factor journals such as Environmental Chemistry Letters, Journal of Hazardous Materials, Environmental Pollution, and Scientific Reports, among others. He has also published numerous chapters and review articles in many books and journals published by leading international publishers. He currently serves as a member on the editorial board of Artificial Cells, Nanomedicine, and Biotechnology (Taylor & Francis), associate editor for Frontiers in Environmental Science (section: Toxicology, Pollution, and the Environment), and review editor for Frontiers in Plant Science and Frontiers in Nanotechnology.
