He was an adviser to NTPC and also to UNDP. He has been an active member for over 40 years in the Geotechnical Committees of the Bureau of Indian Standards. During 1966-1971 he headed the Soil Engineering Section of the Indian Institute of Technology Delhi and guided a number of research projects, in addition to conducting postgraduate programs under USAID, and consultancy jobs.During 1993-1997 he was the secretary and during 1997-2001 the Chair of ISSMGE Technical Committee, TC20 on Professional Practice. In 2001 he introduced the subject of Forensic Geotechnical Engineering at Indian Institute of Technology, Kanpur, India. His first paper on the same subject was presented in the International Workshop on Foundation Design Codes held at Kamakura in Japan in April 2002. He became the Chair of TC on Forensic Geotechnical Engineering, TC 40 during 2005 – 2009. This committee was designated as TC 302 in 2009. He continued to chair this TC until 2013.He is a fellow member of a number of professional societies in India. He has been the national President of the Association of Consulting Civil Engineers (India) during 1989-2003. He is the Founder Chairman of IGS Chennai Chapter. As Joint Secretary of Association of Consulting Engineers (India), he has been involved in the initial drafting of the Engineers Bill.Under his leadership a number of International Seminars/Workshops on Forensic Geotechnical Engineering have been organized between 2005-2013. He has chaired and delivered special lectures in more than eight international conferences and workshops. He also has over 40 published papers in international journals and conferences. He has received seven national awards in India, including a special award by M/S Torsteel Research Foundation, and from Association of Consulting Civil Engineers as also from Indian Geotechnical Society for his significant contribution in Geotechnical Engineering.G.L. Sivakumar Babu is well known for his contributions in research, teaching and consultancy. He completed Ph.D. (Geotechnical Engineering) in 1991 from Indian Institute of Science, Bangalore, India, Master’s Degree (Soil Mechanics Foundation Engg.) in 1987 from Anna University, Madras and B.Tech. (Civil Engineering) in 1983 from Sri Venkateswara University, Tirupati. His teaching and research activities include courses on geomechanics, soil investigations, risk and reliability applications in Civil Engineering, pavement engineering, geosynthetics, and ground improvement.Dr. Babu is Editor-in-chief, Indian Geotechnical Journal and is Editorial Board Member of 1) American Society of Civil Engineers (ASCE), Journal of Hazardous, Toxic, and Radioactive Waste 2) International Journal of Georisk -Assessment and Management of Risk for Engineered Systems and Geohazards, 3) Ground Improvement, Journal of Institution of Civil Engineers, UK during 2006 to 2013 and 4) International Journal of Systems Assurance Engineering and Management. He is a Life Member of Indian Roads Congress, Fellow of Institution of Engineers India, Fellow of Indian Geotechnical Society, Fellow of Association of Consulting Engineers (ACCE), Member of American Society of Civil Engineers (ASCE), Member of International Geosynthetics Society (IGS).He has written a book on soil reinforcement and geosynthetics, edited six books and proceedings and has over 200 publications in journals and conferences to his credit. He received several awards and honors for his work for his work. He received the best PhD thesis award in geotechnical engineering in India bythe Indian Geotechnical Society in 1992. He is a Humboldt Fellow and a DST Boyscast Fellow and a recipient of several best paper awards for the papers published in ASCE journals and journals and conferences of Indian Geotechnical Society.
