Dr. Reddy received his PhD in Civil Engineering from the Illinois Institute of Technology, Chicago. He received gold medals for being first in his class of BS (Civil Engineering) at Osmania University and MS (Civil Engineering) at the Indian Institute of Technology, Roorkee. His teaching and research expertise includes remediation of contaminated sites, waste containment systems, and beneficial reuse of waste/recycled materials. His research contributed to the understanding of fundamental geochemical processes and development of integrated electrochemical technologies to remediate contaminant mixtures. He is the coauthor of Geoenvironmental Engineering: Site Remediation, Waste Containment, and Emerging Waste Management Technologies, also published by Wiley.

Claudio Cameselle is Associate Professor in the Department of Chemical Engineering at the University of Vigo, Spain. He received his undergraduate degree and his PhD in chemistry at the University of Santiago de Compostela, Spain. He then moved to the University of Vigo, where he has been working as a faculty member for the last fourteen years. He spent a sabbatical year as visiting professor at the University of Illinois at Chicago in 2008. His teaching activities are in the areas of chemical engineering and environmental engineering. In recent years, his research activity has focused on the development of electrokinetic remediation for the treatment of soils and sludges polluted with heavy metals and organics.

"The book will serve as a valuable reference for anyone currently working in the field of electrokinetics technology, as well as anyone who is interested in the topic and desires a concise yet comprehensive coverage of the subject." (International Journal of Earth Sciences and Engineering, December 2009)

"The 66 authors have covered the most diverse aspects of this technology in the book, the editors' efforts should be praised, as they have managed to amalgamate the various contributions into a homogeneous, very readable and practical work. The descriptions are clear and understandable, and they are easy to translate into practical applications" ( Land Contamination & Reclamation, February 2010)
