Buddhima Indraratna is a Sri Lankan-born Australian civil engineer and academic specializing in geotechnical engineering. He is a Distinguished Professor of Civil Engineering at the University of Technology Sydney and the Director of its Transport Research Centre. He is recognized for his contributions to transportation geomechanics,[9] particularly rail and road infrastructure, ground improvement, and sustainable use of recycled materials. In 2024, he was appointed a Member of the Order of Australia for significant service to civil engineering.[10][11] He is also the winner of 6th International Civil Engineer Award in 2024 for lifetime outstanding contributions to Civil Engineering (José E. Ibarra Foundation, Madrid, Spain)[12][13] and 2024 Sir John Holland Civil Engineer of the Year (Institution of Engineers Australia).[14]

During the 50th Anniversary of the Australian Geomechanics Society (AGS) in 2022, Indraratna was honoured as an AGS Life Member[15] for outstanding  contributions over many years to the geotechnical community. He is also a Fellow of the Australian Academy of Technological Sciences and Engineering (FTSE),[16] Fellow of the Royal Society of NSW (FRSN),[17] Institution of Engineers Australia (FIEAust), Life Member and Fellow of the American Society of Civil Engineers (FASCE),[18] Geological Society of UK (FGS), Australasian Institute of Mining and Metallurgy (FAusIMM) and Institution of Engineers Sri Lanka (FIESL).

Early life and education

Indraratna was born in Sri Lanka to a family of doctors.[19] He attended Ananda College and later received the Lord Mountbatten Scholarship to study at the United World College of the Atlantic in Wales, UK. His youngest uncle was a civil engineer in the UK and he was fascinated by his drawings, getting him keen to explore more about his drawings and got interested to pursue civil engineering.[19] He earned his BSc (Hons) in Civil Engineering from Imperial College London and went to the industry, realising that his undergraduate knowledge is near the knowledge of understanding complicated field problems when working on dams and tunnel projects.[19] This prompted him to head back to Imperial College London to earn a MSc in Soil Mechanics and Engineering Seismology. He completed his PhD in Geotechnical Engineering at the University of Alberta in 1987.[20]

Academic career

After working as a senior research engineer at the Geomechanics Research Centre in Ontario, Canada, Indraratna began his traditional academic career at the Asian Institute of Technology (AIT) in Thailand (1988–1991), followed by a long tenure at the University of Wollongong for nearly 3 decades.[21] He started doing research on railways once he arrived in Australia when realising that Australia needs significant improvements when compared to the rest of the developed countries and no other researcher in Australia was working on railway tracks.[19] His research caught the attention of railway organisations in New South Wales when the Summer Olympic Games was announced in 1997 and they interested in him doing further research to cater for the higher demand during that time.[19] He later joined the University of Technology Sydney (UTS) as Distinguished Professor and Director of the Transport Research Centre.[22]

Research and contributions

Indraratna is known for his work on:

  • Stabilising soft soils, transport embankments and landslides using principles of ground improvement such as stone columns, prefabricated vertical drains and vacuum preloading[23]
  • Track foundation design, ballast degradation modeling, and lateral confinement using geosynthetics[24]
  • Recycled material use in transport infrastructure, including patented rubber tyre–reinforced foundations[25]
  • Geoenvironmental solutions for acid sulfate soils and groundwater contamination[26]

He has published over 1,100 scholarly works, including nearly 550 peer-reviewed journal articles and 14 books. His work has been cited over 35,000 times, with an h-index of 97.[27] According to ScholarGPS, Indraratna is ranked second worldwide in Geotechnics over the past five years and fourth all-time. He is also listed among the top three scholars of all time in Geotechnical Engineering.[28] In his career, he has successfully supervised over 90 PhD students and nearly 50 Postdoctoral fellows.[22]

Patents and standards

He holds a patent for the tyre-cell track foundation (Australian Patent No. 2018214448),[29] and contributed to:

  • AS 2758.7 (Railway ballast standards)
  • AS 8700 (Vertical drains)
  • AS 1726 (Geotechnical site investigations)
