Mark Cassidy is a distinguished civil engineer whose research has underpinned safe and economic construction of offshore oil and gas platforms. An ARC Laureate Fellow and 2015 West Australian Scientist of the Year, his research contributes to unlocking vast offshore reserves of stranded gas, where the geotechnical response of the seabed sediments is poorly understood. His research outcomes place Mark, and the research teams that he leads, at the international forefront in providing engineering solutions for these problematic soils.
