Prof Harianto Rahardjo

Professor Rahardjo has conducted extensive research on unsaturated soil mechanics to solve geotechnical problems associated with tropical residual soils, swelling and collapsible soils. His current research focus is on rainfall-induced landslides, one of the major environmental problems affecting many countries in tropical regions. This research activity has led to the development of unsaturated tropical soil engineering laboratory in Nanyang Technological University (NTU). He is the co-author of the first textbook on unsaturated soils “Soil Mechanics for Unsaturated Soils”, by Fredlund, D.G. and Rahardjo, H. (1993), John Wiley & Sons, Inc., New York, 517 pages and over 200 technical publications. He has also presented his research works in many keynote / invited lectures and short courses in various countries. He is Core Member of the TC6 Committee of International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) on Unsaturated Soils and Member of the Asian Technical Committee on Geotechnical Natural Hazards (ATC3).
