Contact Dr Dimitris Stagonas
Areas of expertise
- Oil and Gas
- Renewable Energy
Dimitris received his PhD and MSc degrees from the Civil Engineering Department at the University of Southampton, and his undergraduate degree from the University of the Aegean, Greece. Prior to joining Cranfield University in 2019, he was a Research Associate in the Civil and Mechanical Engineering Departments at University College London where he conducted research on the interaction of extreme waves with sheared currents and marine structures, and on the safety of maritime operations in the Arctic. Before this, and for two years he was a research and teaching fellow in Coastal Engineering at the University of Southampton.
He has participated, and in some cases he has taken a leading role, in successful EU HYDRALAB and national research proposals. This funded research dealt with wave & current – offshore / coastal structure interaction aspects utilising experimental and numerical approaches, and it was supported by industry partners like ARUP, DNV GL, Ramboll and HR Wallingford. He has also conducted a strategic analysis of future trends in Arctic shipping, working closely with the MetOffice and Lloyd's Register. Dimitris, sits on the editorial board of the Journal of Maritime Engineering, he is a reviewer for several scientific journals and research funding councils, and a member of the EPSRC peer review associate college.
Dr Stagonas is keen on supervising self-funded PhD projects related but not limited to:
*. Survivability of marine structures
*. Wave - structure interaction
*. Fluid - structure - seabed interaction
*. Marine renewable energy devices
*. Off- / near-shore wave mechanics and wave - current interaction
*. Coastal engineering and structures
*. Future trends in Arctic shipping and safety
*. Offshore and subsea engineering
Dimitris is currently a lecturer in offshore energy engineering. His skills portfolio spans experimental and computational methods in fluid dynamics. In particular, he has proposed new techniques to map the distribution of wave induced pressures, and to accurately produce depth varying currents and extreme waves in experimental and numerical flumes. Dimitris, is also involved in the further development of models reflecting a ship’s fuel consumption and structural safety when sailing in Arctic seaways.
Current research activities and interests include: violent flow interaction with offshore and coastal structures; extreme responses of fixed and floating structures; scouring and subsea engineering; mechanics of breaking waves and wave-current interaction; climate change impacts on current and future marine infrastructure and networks.
He has (co-)authored more than 45 journal and conference articles, information for which can also be found here:
Recently funded research project: Minimising tsunami impact on coastal communities of developing countries. Funded by QR Global Challenges Research Fund. In collaboration with Dr. Liang Yang.
