Sanjay Kumar Shukla is Founding Editor-in-Chief of the International Journal of Geosynthetics and Ground Engineering, Springer Nature, Switzerland. He is Founding Research Group Leader (Geotechnical and Geoenvironmental Engineering) at the School of Engineering, Edith Cowan University, Joondalup, Perth, Australia. He holds the Distinguished Professorship in Civil Engineering at Delhi Technological University, Delhi, VIT University, Vellore, Chitkara University, Solan, Himachal Pradesh, VR Siddhartha Engineering College, Vijayawada, Amity University, Noida, and Amrita University, Coimbatore, India. He has over 25 years of experience in teaching, research and consultancy in the field of Civil (Geotechnical) Engineering. He collaborates with several world-class universities, research institutions, industries and individuals on academic and field projects. As a consulting geotechnical engineer, he has successfully provided solutions to the challenging field problems faced by many engineering organisations. He has authored more than 280 research papers and technical articles, including over 175 refereed journal publications. He is also author/editor of 23 books, including 7 textbooks and 22 book chapters. In 2020/2021, his ICE textbooks, namely Core Principles of Soil Mechanics and Core Concepts of Geotechnical Engineering, have been ranked #1 by Amazon. His research and academic works have been cited well. Shukla's generalized expressions for seismic active thrust (2015) and seismic passive resistance (2013) are routinely used by practising engineers worldwide for designing the retaining structures. Shukla's wraparound reinforcement technique, developed during 2007-2008, is a well-established ground improvement technique. He has been honoured with several awards, including 2021 ECU Aspire Award from the Business Events Perth, Australia, and the most prestigious IGS Award 2018 from the International Geosynthetics Society (IGS), USA, in recognition of his outstanding contribution to the development and use of geosynthetics. He serves on the editorial boards of several international journals. He is a fellow of American Society of Civil Engineers and Engineers Australia, a life fellow of the Institution of Engineers (India) and Indian Geotechnical Society, and a member of several other professional bodies.
