Dr Alfrendo’s recent research activities involved the application of unsaturated soil mechanics in geotechnical enginering in particular related to slope stability, retaining structure and foundation design. He is performing research works through laboratory, numerical analyses and instrumented systems in the field. He is also conducting comprehensive finite element analyses and spatial analyses using geographical information system. One of example is related to the development of slope susceptibility map of Singapore. For his great achievement, Minister for National Development’s Singapore has awarded MND (R&D) Awards 2017 (Special Mentioned Award) for Stability Assessment of slopes covered with Mangrove along Punggol Waterway using Unsaturated Soil Mechanics Principles. Dr Alfrendo has published over 90 technical publications. He has presented his research works in over several invited lectures and short courses in various countries. He co-authored the textbook “Unsaturated Soils Guidelines – Volume 1: Soil-Water Characteristic Curves for Materials Classified according to the Unified Soil Classification System”, by K. Mercer, H. Rahardjo and A. Satyanaga and published by Australian Center for Geomechanics, University of Western Australia in 2019.
