Dr. Jay Ameratunga has been a practising civil engineer for over 35 years specialising in geotechnical engineering. After graduating from the University of Ceylon, Peradeniya in Sri Lanka, he obtained his Masters at the Asian Institute of Technology, Bangkok, and obtained his PhD from Monash University, Australia. Early part of his career was spent in Sri Lanka before joining the Coffey Group in 1989. He has been involved with the investigation, design and construction of many major projects, especially in Australia and New Zealand, including the Gateway Upgrade Project and the Future Port Expansion Seawall Project in Brisbane, and the State Highway 16 Project in Auckland. He works closely with universities on major research projects and mentors PhD students and young engineers. He has also been a visiting lecturer at Queensland University of Technology, Brisbane. He has co-authored close to 50 technical papers on soft clay, reclamation and ground improvement and has presented in conferences in Australia, New Zealand and at other international venues. He is a Past Chair, Australian Geomechanics Society, Queensland Division, a member of the Australian Standards Committee for Geosynthetics and a Fellow of the Institution of Engineers, Australia.
