    • Short Resume:

    Dr Jayantha Kodikara's expertise is in the areas of Geotechnical, Geoenvironmental and Pavement Engineering. He received his BSc (Eng) degree (1st Class Honours) from the University of Peradeniya, Sri Lanka in 1983 and PhD degree in Geotechnical Engineering from Monash University in 1989. His PhD was on the side resistance development of piles socketed into Melbourne mudstone. He worked on finite element analysis of soil-structure interaction problems, as a Post-doctoral Research Fellow at Newcastle University from 1989 to 1991. He also worked as a Senior Geotechnical Engineer with Golder Associates Pty. Ltd., Melbourne, Australia from 1991 to 1994, where he was responsible for engineering analysis of geotechnical and geo-environmental problems, management of projects including development and maintenance of computer programs. His present work at Monash includes supervision of doctoral, masters and undergraduate research projects and conducting fundamental and applied research. He has published over 120 technical papers on a diverse range of topics. He has attracted over 3 million dollars in external and internal research grants, during his 10 year tenure as an academic. He is a Chartered Professional Engineer in Australia and has served as honorary treasurer in Australian Geomechanics Society. His current research interests include; stabilisation of soils and rocks for road pavements, geomechanics featuring soil suction, behaviour of compacted soils and rocks, evaporation and cracking of soils, leaching and migration of contaminants in porous materials, pile foundations and numerical modelling.
