Professor Ian Johnston
- Geotechnical Engineering, Geothermal Energy
Professor Johnston obtained a Bachelor’s degree in civil engineering in 1968 and a Ph.D. in 1972 from the University of Southampton (UK). After 3 years in industry, he joined Monash University where he was a lecturer, senior lecturer and associate professor. In 1993, he was appointed Professor and Dean of Engineering at Victoria University of Technology. In February 1998, he returned to full time consulting with Coffey Geotechnics where he was a Senior Principal. He joined the University of Melbourne in May 2009 as Professor of Geotechnical Engineering.
Although Professor Johnston’s consulting and research interests have covered a wide range of topics, he is probably best known for his work on soft, weak and weathered rock in civil and mining engineering. He has made many presentations on this general subject and others at local, national and international conferences. He has published over 100 technical papers including about 60 in refereed international journals. He has undertaken substantial consulting work on a wide range of projects in Australia and overseas both as an academic and as a consultant. He has also had considerable involvement with forensic geotechnical engineering and matters involving expert witness services for litigation and arbitration.
In February 2012, Professor Johnston was appointed a member of the Technical Review Board which has a primary function to provide independent advice to assist the Victorian Minister for Energy and Resources and industry better manage ground control associated with mining in Victoria, in order to mitigate the risks this presents to public safety, environment, public infrastructure and security of power supply.
Since returning to a full-time academic position in 2009, Professor Johnston has developed a strong interest in direct geothermal energy (or geoexchange) in which the ground relatively close to the surface is used as a source and sink for heat to heat and cool buildings. His rapidly growing research group is developing several instrumented field test sites around Victoria to provide performance data for these systems under varying conditions. It is intended that this data will lead to more efficient and effective design methods for Victorian and Australian conditions.
He has been the recipient of several teaching and research awards including the E.H. Davis Memorial Award from the Australian Geomechanics Society in 1991 for "distinguished recent contributions to the theory and practice of geomechanics in Australia". He was also the recipient of the Australian Geomechanics Society’s highest award, the John Jaeger Memorial Award, in 2012 for “contributions of the highest order over a lifetime commitment to the geotechnical profession in Australia”. He has held offices in several learned societies, professional associations, educational boards, advisory panels and standards committees including the Founding Editor of Australian Geomechanics, Chairman of the International Society for Soil Mechanics and Geotechnical Engineering Committee on Soft Rock and Vice President and Board Member for Australasia for the International Society for Rock Mechanics.
