Dr. Pradeep Kumar is currently working as Associate Professor at Indian Institute of Technology (Banaras Hindu University), Varanasi. He has done his PhD from IIT Roorkee and Post-Doctoral Fellow from University Sains Malaysia, Malaysia. Dr. Kumar has awarded 2 PhD degrees and 20 PG degrees. At present 3 PhD Scholars and 2 PG students are undergoing research projects. He has successfully completed Rs. 70 Lakhs projects and Rs. 30 Lakhs (in progress). He has published 35 research articles and participated 14 international conferences. He is also working on the socioeconomic dynamics governing urban energy and urban land use in secondary cities of India. Pardeep Singh is Professor and Head at the School of Advanced Chemical Sciences, Shoolini University, Solan, India. He is specialized in physical chemistry and heads a lab of research scholars who work on photocatalysis with the aim of generating new knowledge on graphene-based photocatalytic materials and processes to develop novel de-pollution treatments with enhanced efficiency and pilot-scale applicability. He is also exploring the generation of bio-waste material-based activated carbon for adsorption-based removal of aqueous phase pollutants. Professor Daniel A. Vallero is an internationally recognized author and expert in environmental science and engineering. He has devoted decades to conducting research, teaching, and mentoring future scientists and engineers. He is currently developing tools and models to predict potential exposures to chemicals in consumer products. He is a full adjunct professor of civil and environmental engineering at Duke University’s Pratt School of Engineering. He has authored 20 environmental textbooks, with the most recent addressing the importance of physical principles in environmental science and engineering. His books have addressed all environmental compartments and media within the earth’s atmosphere, hydrosphere, lithosphere, and biosphere.
